Should i forgive my dad?

My dad is bipolar and has been arrested over 30 times for numerous things-assault, aggrivated battery, attempted murder, tresspassing, violating perole, violating O.P., endangerment of a child, stalking, the list goes on and on. I haven't seen him in over a year after he had been verbally attacking me and physically harmed me. Then he was arrested and tried, but got out on bail. We have had many problems in the past 2 years. And after all the things he did to my mom, he smashed her head through a wall, yelled at her, and noe she is deaf in one ear. He pushed her down 38 stairs, stalked, harrassed and everything. But that is just the bipolar disorder combined with some other mental issyes he has. I used to have good times with him, and I remember them. I miss his blue eyes and I wish to see them again. He was a nice guy and funny, loving, the best dad in the world, sometimes. But now I miss him soooo much. My mom told me he's in dominican republic because he has to do community service for something with his invalid passport IDK. But he called me and he acted like nothing ever happened!? But something didn't feel right about that phone call, as nice as it was. I don't know if it was the right choice or if I should let him back into my life? I know he loves me, but I know he can't get ride of bi polar disorder and all.
