Characterization of Mother in A Man Named Dave

Dave Pelzer's mother is concluded to be a terrible human being. She attacks Dave for no reason and makes him do beyond awful things. In A Man Named Dave, she is most definitely the antagonist for obvious reasons. The weirder thing is that she has another son and treats him perfectly fine. I would also be scared if I was David's brother because this monster might turn on me any second.

David's mother eventually passes away after her kids were separated from her. Dave says now that his mother's actions were caused by her own childhood and how she used to live.
