While I agree with some that nothing is inherently good or evil--for it would mean that the Universe itself placed these labels upon certain actions, violating Hume's is-ought dichotomy--but I do believe that people inherently want to please others and want to limit harm to others, at the very least, to those around them

Virtually every human conceives of himself/herself as "good," no matter how they define it or if it contradicts someone else's definition of good. People would sooner adopt a belief system which defines their actions as good rather than confronting any moral evil they've committed. For instance, instead of defining one's self as evil in the eyes of one's parents' religion, one would sooner drop that religion than bathe in the darkness of moral decay, maintaining that world view.

The majority of the world (84% the last time I checked) is religious. Whether they believe that it is one's duty to be good for the sake of being good, whether they believe that obedience to a higher power is the greatest good, or whether they just like the feeling of being good, the majority of people join religion for moral reasons. Even the atheists and agnostics who oppose religion do so with moral arguments.

The fact that people do stupid, crazy, and evil things is not a result of people not wanting to be good.
