Years ago, I was in a gaming group where
unquietsoul5 was the most frequent GM. In one of the games he ran, I played a spellcaster. One of this character's best spells was a spell which caused an NPC to act as the best, noblest form of him- or herself that was available. So, for instance, when my spellcaster was captured by the bad guys, he cast this spell on the guard. The guard was not willing to let my character go, because, as he explained, he had agreed to guard me, and he was certainly not going to just flake on what he had agreed to do, but he was willing to make a phone call to the other PCs to let them know that I had been captured, but I was otherwise safe.
The ability to bring out the best in people, including in the people you more-or-less oppose, doesn't solve everything. After all, people of good faith, both honorable and decent, may disagree about what the best course of action is, and come into direct conflict over it.
But it DOES have a tendency to get rid of a lot of the STUPID conflicts. Not always: I think WWI is an example of a stupid conflict that came out of . . . okay, fine. I don't actually understand what WWI is an example of. (I USED to understand what it was about, but then I learned more. The more I learn about stuff, the less I understand it.)
Sorry, digression. Anyway, the ability to bring out the best in people is a useful superpower.
There were times today that I displayed it.
