Allison is the worst character I have ever seen

This is my first time watching teen wolf and I just finished season 2. Allison is the worst character ever, she made it hard for me to get through the season. And the fact that she was so easily forgiven just drove me nuts. She turned on everyone, didn't even apologize to the people she hurt and didn't even accept she did anything wrong. What a psychopath, like it literally enrages me. If they still continue to trust her after this season I don't think I'll be able to watch because she's already betrayed them twice. She has no sense of self and is influenced by literally anybody. What a piece of shit.

Edit : I also really dislike Scott for not yelling Allison that her mom tried to kill him. He just let her hate Derek for no reason. A lot of stuff could have been avoided if he just grew some balls.
