Natural Law: Does human nature have an orientation to good?

Evaluation

This is a difficult question to answer, as 'good' is a hard thing to define. Most people are generally 'good', however, we have all say, told a lie. Does that mean we are still good? We are all contributing to the damage of the earth, we can all be selfish and greedy from time to time. Some people are even worse, being murderers and criminals.
