Yes. I believe I read that line in Richard Bach's Running from Safety. His idea is that there is no such thing as Good and Evil (or right and wrong), only what makes us happy and what makes us unhappy. Happy, being a state of well-being.
In instances when one performs an act he knows to be evil (kill someone), but does it anyway because it makes him HAPPY, then it is NOT GOOD. This is because happiness is viewed as long term, meaning it involves the consequences of his actions. If he thought about the consequences beforehand (getting caught by the police, sent to jail), then he will see that the consequences will NOT make him happy. Thus, it is evil.
That's my understanding of his point. If there are any mistakes to how I interpreted it, I welcome the corrections.
