That is... so basically every human is born evil because every human, at one point in their life has done something selfish, however small and minuscule it may have been. But that is just the way of the world, so in one word the world is evil?

That is a [b]very[/b] broad categorization of evil. You can't just call the way nature works evil. Putting yourself before others is survival at its basics. So survival is evil?
