I am quick to forgive someone who apologizes, or even without apology if I can tell whatever happened was not in that person's nature or they regret it.

I have a much harder time forgiving someone who isn't sorry, who doesn't regret the hurt feelings they've caused, or who is unaware of the hurt they cause when I feel they reasonably should be (i.e., people who generally lack empathy or any sort of awareness about the feelings of others).

It has occurred to me more than once in my life that I have an overinflated sense of justice. I will get raging mad on behalf of someone I know/love, a friend, an acquaintance, or even a total stranger I read about if I feel like there has been an injustice or other hurt done to them. I don't know how to turn that off - it's a total flashpoint for me.
