Let's say that a pair of twins is born. They are identical in every way. The difference is this:
As they grow, Twin A is taught right from wrong, while Twin B is allowed to do whatever he wants.
Which twin will most likely grow up to be a "good" or even a "decent" person?
The Lesson: All of us are born with the inclination to do wrong. We have to be TAUGHT not to do wrong things. How interesting.
