Okay, well consider this for a moment:
Alright, we now have superheros in the World. More precisely, just one. Say that superhero ends up in ............ oh, I don't know....North Korea? It's a matter of assumption that superheros are morally good willed, honest, trustworthy, always does the right thing.....now let's take a look at this senario (sp?) through an outsiders eyes. To the hero, N.Korea looks like it's being opressed by the other nations of the world. The hero could see this as a threat, and fight for these opressed people. Now what do we do? We've got a superhero using thier powers for what they think is right, good, and just based on what they see first hand. I won't even go into what would follow next. The world as we know it would be changed forever. We as a race certianly wouldn't be able to stand up against this hero, and only until it's too late will he/she fully realize what has occured.
