Actually, it is only when Jesus the meek and mild arrives in the bible, that we learn that there's a problem in not believing in the religion after you are dead, and Jesus makes it perfectly clear that it either is his way, or the hellway. I constantly hear a lot of times that you know, jesus wasn't a god or anything, but he was pretty okay as a dude, nice chap and all. And no, no he wasn't. He was petty, egomaniac and utterly self-righteous, damning everyone who didn't believe him to the everlasting fire.
I'm not, obviously, talking about the "real" Jesus, but about the Jesus as portrayed in the Babble.
