Spoiler Warning: This article discusses Cathy Ames and major events in Netflix’s East of Eden.
Is Cathy Ames evil?
For readers of John Steinbeck’s East of Eden, that question may sound almost unnecessary.
Cathy has long been remembered as one of the novel’s most frightening characters — a woman Steinbeck presents in deliberately monstrous terms, seemingly lacking the kindness and conscience that restrain ordinary people.
Then Netflix changed the question.
In Zoe Kazan’s seven-episode adaptation, Florence Pugh’s Cathy is still manipulative, destructive and capable of terrible choices.
But the series also asks viewers to look at something Steinbeck treated very differently:
What happened to Cathy before she became the person everyone fears?
That change has become one of the biggest debates surrounding Netflix’s East of Eden. The Los Angeles Times noted that much of the discussion around the adaptation has centered specifically on Kazan’s decision to humanize a character traditionally regarded as an embodiment of evil. Los Angeles Times
And the change is not accidental.
Netflix’s version is deliberately asking whether understanding evil is the same thing as excusing it.
How Evil Is Cathy in Steinbeck’s East of Eden?
Steinbeck does not introduce Cathy as an ordinary person who slowly becomes corrupted.
He makes her disturbing almost immediately.
The novel repeatedly connects her to the idea of a person who appears human but is somehow missing the moral instincts that other people possess.
Even Netflix’s own trailer acknowledges this famous interpretation, opening with language about monsters being born into human families and children existing without kindness or conscience. Netflix
That idea matters because Cathy functions as more than simply an antagonist.
She is part of Steinbeck’s larger argument about good, evil and free will.
Adam sees something in her that may not exist.
Other people underestimate her.
Cathy learns how to manipulate those weaknesses.
The frightening possibility in the novel is that there may not be a satisfying explanation for why Cathy is Cathy.
What if some people simply choose evil?
Netflix complicates that idea.
What Did Netflix Change About Cathy?
The most important change begins with Cathy’s childhood.
Zoe Kazan has explained that when she reread Steinbeck’s description of an incident involving the young Cathy and two boys, she interpreted it differently as an adult.
Rather than viewing the scene simply as evidence of a naturally manipulative child, Kazan saw signs of trauma and psychological dissociation.
Netflix consequently reframes Cathy’s childhood around the lasting effects of sexual assault. Her fascination with Alice’s Adventures in Wonderland also becomes psychologically significant: the fantasy of becoming smaller functions as a kind of imagined escape from a world in which she does not feel safe. Los Angeles Times
That is an enormous change.
Because once Cathy has a traumatic past, viewers are given something Steinbeck often refuses to provide:
a possible cause.
Why Did Zoe Kazan Humanize Cathy?
Because Kazan appears less interested in asking whether monsters exist than in asking how people become monstrous.
Netflix describes this adaptation as giving new attention to Cathy Ames rather than leaving her on the edges of the Trask men’s story. The series was conceived from the beginning with Cathy as a central figure. About Netflix
That shift changes the storytelling problem.
A novel can describe a character from the outside and allow that character to remain mysterious.
A seven-episode television series centered partly on Cathy has to spend much more time with her.
Kazan has also spoken about one of the fundamental difficulties of adapting Steinbeck: prose allows readers direct access to characters’ thoughts, while television must express those thoughts through behavior, dialogue and images. Netflix
So Netflix gives Cathy interiority.
We don’t merely watch what she does.
We are encouraged to wonder what she experiences.
And that inevitably makes her more human.
Florence Pugh Also Refused to Play Cathy as Just a Monster
Florence Pugh’s approach reinforces the adaptation’s decision.
Pugh has said she takes pride in giving unlikeable characters another chance — trying to understand their decisions and finding empathy for them without reducing their entire existence to their worst actions. Netflix
That’s an important distinction.
Empathy is not innocence.
Understanding why Cathy behaves a certain way does not mean saying that what she does is acceptable.
Netflix does not erase her cruelty.
It changes the perspective from which we observe it.
Instead of:
Cathy does terrible things because Cathy is evil.
the series invites another possibility:
Cathy does terrible things. What combination of trauma, personality, choice and circumstance made her capable of doing them?
Those are very different questions.
Does Netflix Make Cathy a Victim Instead of a Villain?
Not exactly.
This is where some of the criticism of the adaptation becomes interesting.
If every cruel action receives a traumatic explanation, there is a danger that Cathy’s defining quality disappears.
Steinbeck’s Cathy is frightening partly because readers cannot comfortably explain her.
There is no simple equation:
trauma → Cathy → evil.
Netflix moves closer to providing such an explanation, but it does not completely absolve her.
Cathy still makes choices.
She still hurts people.
She still manipulates those around her.
She remains what Netflix itself describes as the “dark star” around whom Adam, Charles and others revolve. Netflix
The adaptation therefore creates tension between two interpretations.
Cathy as victim.
And:
Cathy as perpetrator.
The uncomfortable answer may be that she can be both.
Why Are Book Fans Arguing About This?
Because changing Cathy changes one of the philosophical foundations of East of Eden.
The story is heavily concerned with free will.
Are people condemned by their nature?
Are children condemned to repeat the sins of their parents?
Or can someone choose differently?
That question eventually leads to one of the most important ideas in the entire story: timshel.
“Thou mayest.”
Choice.
If Cathy is simply born evil, she represents one extreme of that debate.
But if Netflix gives Cathy trauma, social pressures and psychological wounds, her behavior becomes more complicated.
Now viewers have to separate three things:
what happened to Cathy,
what Cathy became,
and
what Cathy chose to do.
That is why changing her childhood isn’t merely adding backstory.
It changes how we interpret the moral argument of the entire story.
Is Cathy Really Evil?
Yes — if by evil we mean that Cathy knowingly commits cruel and destructive acts.
But Netflix rejects the idea that this is the only useful thing to know about her.
The adaptation asks viewers to hold two ideas simultaneously:
Cathy has suffered.
And:
Cathy causes suffering.
One does not erase the other.
That’s arguably the most important difference between Steinbeck’s Cathy and Florence Pugh’s Cathy.
Steinbeck frequently asks us to confront a frightening possibility:
What if a monster can simply exist?
Netflix asks a more contemporary psychological question:
What if calling someone a monster prevents us from understanding how that person became one?
Neither question necessarily excuses Cathy.
But they produce very different versions of the same character.
Netflix Changed Cathy — But Not the Question of Choice
This may be the key to understanding Zoe Kazan’s adaptation.
Netflix has not transformed Cathy into a misunderstood hero.
It has transformed her into a person viewers can understand more closely.
That distinction matters.
A traumatic childhood can explain behavior without justifying it.
Victimhood can coexist with responsibility.
Empathy can coexist with judgment.
And a human being can suffer terrible things and still make terrible choices.
That is why Netflix’s Cathy feels so different.
The series doesn’t necessarily ask us to forgive Cathy Ames.
It asks us to stop using the word “monster” as the end of the explanation.
And once we do that, East of Eden becomes uncomfortable in an entirely new way.
Because the hardest question is no longer:
Is Cathy evil?
It becomes:
How much of Cathy was made by what happened to her — and how much did she choose?
That question takes us directly back to the central idea of East of Eden:
Can human beings choose what they become?
