Why!
It's funny isn't it? We humans are so inventive and imaginative we have come up with ways of curing complicated deseases and even gone to the moon. but we can never seem to learn to accept our differences....and it makes me wonder is it just "the survival of the fittest" that haunts our progress, making every humans life a constant competition? Or are we nature's greatest mistake? when we spend most of our time creating methods and weapons to defend ourselves against ourselves? When there is so much more to this world than just ourselves?
Well maybe there is a paradise somewhere, and this must be some kind of test. If you manage to live through your life without hurting too many people and not to give up. The paradise might just be the reward......or.....I don't know!
