My character, Bishop, is basically a man who has lost everything. And who only refuses to end himself because that would be the coward's way out. It just so happens, that he tends to help people along the way.
As it stands, the only things he enjoys in life are guns, alcohol, and women. But at the end of it all, he's waiting for final confrontation that he doesn't walk away from. You can be that anyone else involved won't be walking away either.
