Why is the "good people" much more than "bad"?

If a person does something that is considered poor in his company - in most cases, he realizes that went bad. It's an obvious thing (because it is often even hardened criminals are aware of what they are doing evil). And it paves the way for a commitment to reform, leaving the person so to speak on the "light side".

And how many people who believe that bad and evil deeds is good? Chances are very few of them - the mentally ill, maniacs, some "fighters for justice."
