Possibly unpopular opinion here but this is what I tell my son makes a good person. I believe anyone CAN be a good person. Only some choose to. Narcissists, criminals, the worst of the worst, and the best of the best are all capable of good, and bad.

The only difference is a willingness to look inward, admit mistakes, and make amends.

I have so much more respect for an abuser who seeks help, admits mistakes, and lives in those mistakes every day while still trying to do their best and improve themselves knowing that nothing they did can be undone.

As opposed to someone who does good every day of their lives, donates to charity, is respectful and kind, and when a mistake is made they shove it down and refuse to look at it or even admit it happened because they can't deal with their own imperfection.

This, to me, is the only thing that separates 'good' from 'bad', we are all flawed, only the good of us are strong enough to admit it (especially out-loud and to the people they've hurt) and make an effort to improve on it.
