No, I would probably begin by embezzeling funds from everywhere I could get my hands on. I'd "key" every car that was parked funny. If somebody pissed me off, I'd just haul off and punch them in the face. If I got very depressed, I'd probably end up going on a killing spree instead of just doing myself in. In short, I'd do whatever I could get away with, because I could be totally solopsistic.
Well, I would not. I do not. If the above is true then you are a person who only behaves civilly under threat of punishment (hell) and not someone I would trust or associate with.
I believe that most people are intrinsically "good" and do not need the threat of punishment to behave decently. As far as people like you are concerned, I am grateful that we do have religion if for no other reason than to keep you in check.
