[DC, Marvel, Image, etc] Why do people commit evil acts despite the fact that heaven and hell are proven to exist?

Do they not care, do they not know, or are they just insane? If you're mortal and you have limited time on your planet then you'd think that you would do everything possible to avoid being tortured forever.

There are plenty of awful people who believe they're going to Heaven.  Beyond that, not all behavior is reward-seeking.  Some philosophers might even argue that proving the existence of the afterlife would be corrosive to the concept of morality if it reduced all human behavior to merely avoiding punishment.  

Someone defined by their pride, like a Wilson Fisk or a Lex Luthor, would certainly recoil at the idea.  It's easy to picture them waxing quite Byronic if the existence of Heaven and Hell were ever proven to them.  They'd take their chances on going to Hell and plotting a hostile takeover when they get there.
