Superman was sent away from Krypton because it was going to explode. I can see how similarities can be made, but the essence of the story is completely different. Jesus' story is about sacrificing himself to save everyone from their sins. Sure Superman follows a similar ideology, but Jesus didn't fight people. And every time Superman meets ANYONE, friend or foe, you can bet Metropolis' wallet will weep as shit gets DESTROYED. Honestly, can't he just sit down and try to talk it out once in a while? I know that doesn't make for a good comic or movie, but he's stuck in a cycle.
