There is a strong tendency for an evil person to consider himself good, and for a truly good person to consider himself bad. The rationale behind this is simple: Their criteria of good and bad differ greatly.
A good person desires to help others, and when unable to do as much as he idealistically wishes, considers himself “bad.”
An evil person considers himself “good” if he refrains from beating someone up after taking their money.
The lesson: Be objective about your actions.

Not sure I totally agree with this person. I think a person can consider themselves good if they use the group’s mindset of good without weighing the pros and cons within themselves. A lot of folks automatically label things “good” and “bad” and never give it another thought because some authority tells them that’s how things should be defined. The truly “good” person will struggle with the moral issues, even when it’s painful, because that’s when they actually take ownership and responsibility for their own attitudes, decisions, and actions.
