I know this is sexist, but IMO she is eviler than him. She is a woman and a mother. I find her too be a monster!
It does seem sexist. He spent how long fooling her into thinking they might have a future? He had a child with her. He beat her brains in while pretending she was going to guess candle scents. As her baby was nearby in another room.
I think of the innocence and vulnerability of KB. No family around. No friends nearby. Hopefully waiting and being strung along, thinking he really was her fiancée and they would make their family "official".
Probably being gaslighted. Having to go to a hospital for anxiety and depression as her dreams never materialized and she realized the trap of being away from friends and family in the state of a man who probably didn't love her, raising their child together. Likely not being accepted by his family. Definitely not his mother.
And yet she still hopes. She is alone on Thanskgiving morning with her baby. She gamely makes some cinnamon buns. Perhaps in an effort to be festive. Or hopeful that she will be invited to the family dinner.
But PF says they will celebrate together. So she at least won't be alone. She buys flowers, though, that afternoon. Still thinking she might have an opportunity to win over his recalcitrant mother, for whom I'm betting no woman is good enough for her baby boy.
He comes over. Asks her to play a fun game. She agrees. Allows herself to be blindfolded. Thinks it might be fun. And as she stands there with the father of her child nearby and her baby down the hall and waits for a scent that never comes, she suddenly experiences something very different. The man she hoped to marry and raise a family with just beat her head in with a blunt object. No candle scent. No fun. Just pain.
PF did that. Not KK. He did that to the mother of his child. To a woman who thought she was his fiancée.
The person who helped him clean up the scene and cover up the crime doesn't rise to the level of the evil of a person who betrayed the trust and took advantage of the vulnerability of the woman he knew and bore a child with.
I do think sexism is partially to blame for the steadfast determination to find KK guilty of murder.
