I want to be friends with oj simpson
That's a strange thing to say. Why would you like to be friends with him?
I really want to try to understand why he did what he did
I understand that people sometimes are fascinated by alleged murderers. However, I'm not sure you need to be friends with him to find out.
Nah he's cool.
I don't know him personally, but I think it's better to be safe than sorry in this instance. He is an alleged murderer who has been in prison for other things, so it might be best to not become friends with him.
