Why does it seem like there's more evil/bad people on earth then good?

I have wondered this many times myself. I think, maybe, it is because many people seem unable to not become mean when they feel they have been hurt. It takes strength and courage to still care about others when it seems like no one cares about you.When you lose the ability to care about others it is very easy to become mean. Evil is another story.I believe truly evil people are born that way,but there does seem to have been an increase in those born evil,in the world today.
