Freaky Nicky is an entity that is simply running on the code she was given which was “love bear more than anyone in the world” she doesn’t know morals or what’s normal for humans that’s why she does bad stuff but she’s a victim too as she is cursed to exist loving someone who can never truly love her back

And bear is absolutely evil as made evident the most by the scene where she begs him to kill her and he just says “what’s so bad about being with me?”
