Wow, lots of good insights! I highlighted a few.

We don't often think about it - and often even develop mythologies that obscure the matter further - but the underlying reason why we hold grudges and seek revenge is to protect ourselves from harm.

And so the first precondition for forgiveness - rather than possessing a superpower - is actually, simply having the confidence that the person who wronged you has changed, such that you feel you can trust them going forward. That's one of the roles that an apology can serve. A good apology can provide evidence that the person understands that they caused harm, and intend not to do it again. I wrote a small section in another article* called 'A “Proper” Apology Is Hard Because Changing a Mind Is Hard', which touches on this a little more.

I think the superpower required isn't in the actual act of forgiveness per se, but rather, it is the ability to look beyond our animal instincts and social mythologies to see what actually matters in life, which is I think what you've demonstrated in those parts that I highlighted.
