There Is Almost No Situation Where Hatred Helps

Marcus had the short version in Meditations 6.6: the best revenge is not to become like the person who wronged you.

Hatred keeps you tied to the person you resent. You pay for it in your own nervous system long after they've moved on.

Correct — and the uncomfortable corollary is that most people who preach this aren't free of hatred. They've just outsourced it to whoever they vote for, buy from, or cheer for. Clean hands, hired hatred.

Hatred tends to keep us rehearsing a conflict long after it ended, which costs focus and sleep. Letting go has been a practical choice for me, not only a moral one.

Marcus Aurelius put it in one line in Meditations: the best revenge is not to become like the one who wronged you. Hatred tends to do the opposite, slowly shaping us into a copy of what we resent.

Hatred is just bad energy management. It makes you irritable, reactive, and sloppy. Discipline isn't about hating who you are, it's about respecting what you're building.
