Okay, so he wants to help people because a Hunter helped him as a kid and showed him that being rebellious (I'm guessing bad rebellion, like dipping into crime and stuff, otherwise the notion wouldn't make sense) probably wouldn't get him much in life, and his goal is to repay the kindness shown to him by the Hunter, so he became a Hunter to help others.

Good start on a backstory and personality, which can be the hardest part sometimes. Now just keep building from there, keep it simple instead of going super overcomplicated (which is what happened with Carmine, I think), and you should be right.
