"I often run across memes online with the phrase “Hurt people hurt people.” This means that people who have been hurt turn around and hurt others. It is assumed that since they’ve never experienced any healing from the hurt, or even justice for it, the wound festers and they respond by hurting others.

I sympathize with the rationale behind “hurt people hurt people.” It’s hard to be sensitive to other people’s pain when your own has never been completely healed, or the ones who hurt you seem to continue on happy and healthy as if nothing happened."
