“When people injure you, ask yourself what good or harm they thought would come of it. If you understand that, you’ll feel sympathy rather than outrage or anger. Your sense of good and evil may be the same as theirs, or near it, in which case you have to excuse them. Or your sense of good and evil may differ from theirs. In which case they’re misguided and deserve your compassion. Is that so hard?”
It's not your job to hold anyone accountable. That will be handled by life, nature, when they stand before God, however you want to look at it.
No, your job is to do right by them as a person, a person no different from yourself.
Remember to take time to consider why somebody does something, what good or harm they thought would come from it. Consider yourself in their position, but more importantly, from their perspective. Not their perspective with information or insights that YOU might have, but their perspective as they see it.
You might find that you can appreciate where they are coming from, and understand how you might feel and act similarly if you were in there shoes.
And if you still would not choose the path they have chosen, show compassion.
Anger is an incredibly destructive force, to the self most of all.
When you have anger toward another person, the idea of excusing or showing compassion to them seems very, very hard. You convince yourself that to excuse somebody or show them some compassion would be an injustice to the cosmos, when in reality is is only an injustice to your own oversized sense of self-righteousness - your ignorant belief that you are somehow better than them, sitting and observing their situation from afar.
But when you can lay it all aside, and see another person for who and how they are - your equal, in different circumstances - compassion is so liberating. It is so easy. Anger weighs you down. Knowing that you are not doing right by another person weighs you down. These are difficult to carry. These weights are with you everywhere you go.
Until you let them go.
I’ll leave you with one parting thought from Meditations:
“To feel affection for people even when they make mistakes is uniquely human”
