<human>: Could you distill the essence of the text into 1-3 sentences?

Throwaway just because I can.

My entire life, my brother has been physically abusive towards me. He's tried stabbing me, I've gone to school with so many cuts and bruises consistently that the school wanted to get police involved (when I was in high school and he was graduated), and he's overall, a huge dick. 

A few years ago, around the time my mom died from cancer, I decided to cut my brother out of my life. I don't talk to him and I avoid being around him at any family gatherings. It's worked for the most part, up until last year when I was at my dad's place for my birthday dinner and my brother showed up drunk (he's an alcoholic) when he wasn't invited. I asked him to leave and next thing I know I was on the ground getting my face kicked in. Since then my brother has gone through government mandated rehab and I still haven't talked to him since. The most interaction we have is we still give each other gifts at christmas and on our birthdays (albeit through the mail).

My brother recently had a baby with someone he's been dating since he got out of rehab and my entire family is pressuring me to forgive him and reconnect with him, for the sake of my nephew. Honestly, I could care less about my brother's life and would rather continue not being involved in it, even if it means not being part of my nephew's life. Alas, it's turning my entire family against me. My sisters hate me for taking part in my one nephew's life (my eldest sister's son) but not the other's (my brother's son), and my dad is just really disappointed. I just can't get over the years of abuse and beatings that my brother had given me. 

Am I wrong for not wanting anything to do with my brother's life, even now that he has a baby?
