In all honesty I think if people thought there was no god or afterlife they would go crazy, I know there are a ton of people id like to shoot and get rid of but that isn't my right god commands all not to kill each other lest in self defense. I also do not believe any religion I think god put the rules in us from the begining and you know whats right and wrong.

Dont steal
Dont Kill
Dont Cheat
etc
