What do you win? That you lived your life as a scumbag murderer?If I murder 100 people and never get caught by the police and die, if I am wrong about an afterlife, I lose. If there is no afterlife and murder 100 people, I win?
Belief in a final punishment is what most people fear, or there would be thousands of murders/rapes a day, you think? If I base my life believing in God and have an eternal soul, and am wrong, I lose nothing, but that's a pair of dice I do not wish to roll.
Not commenting on any final judgment's of anyone, but rapists and murders do not worry about an eternal soul, Hitler didn't.
There already are thousands of murders/rapes a day
Rapists & murderers are not the only people doing "evil" deeds to their fellow humans. You don't have to look far for examples.
