Super heros

What is it about human nature that makes us want to be "super"? Our world is obviously consistent, good vs. evil. Yet, the lines get blurred so often. And what about love? Are evil people capable of love? Are people capable of being truly evil?
These are the questions that run through my mind as I watch "Unbreakable", M Night Shaylaman's ode to comic books. These questions also popped in my head as I read "Justice" by Faye Kellerman. In this book I was more drawn to the "villain" than the hero. The reason? He was a product of his environment. Plain and simple, he was broken. Young and trapped in a life that never allowed him to love, at least not without it resulting in death.
I guess, no I know, I am compassionate to a fault. My compassion got me my kid, and in a world that is obviously good & evil, compassion just might be what keeps me good and not evil. But hey, that's just me.
