^It does. The Penance Stare won't work on those who doesn't regret anything and Punisher doesn't regret all the criminals that he has killed.

As long as you regret. The Penance Stare works, hell in fact believe it or not but it would actually work on Aang. Now I know what your thinking. "Isn't Aang pure-hearted?"

Yes, he is but there were things that he has regretted. Among them was he didn't come for his people and has technically been responsible for the deaths of many people for 100 years, felt bad for having to hurt people in the avatar state and most of all regretted using Fire Bending the first time when he accidently harmed Katara.
