I think maybe 10% are 100% sure there is no God and therefore they will be little more than food for worms. I bet 60% would never admit it, but personally are not sure, and would normally hedge their bets in one way or another, by at least from time to time try to be decent human beings.
I believe everyone is born good with a conscience that is given to them by God. It’s those who have it driven out of them because they have no faith, ultimately chose to be evil. Democrats believe the end they deem to be good for themselves justifies their evil means. They have no faith.. no conscience. Sucks to be them!
