So are you saying the only reason you try to be a decent person is because of the words of the bible and because you'd like to go to heaven?
if either of those were (theoretically, obviously) demonstrated to you to be false, you would just go on a rampage, killing, stealing, raping to your heart's desire?
By the way, if we're going to talk about right and wrong, groups v individuals, the founding fathers, etc., we should probably be a bit more clear about what we're discussing. Is it ethics / morality or the law, for example? (Because while there is overlap, the two are different)
