“As with all internal experiences, being mindful of what you are experiencing is the first step. Thoughts of revenge apparently feel good and may be a basic human instinct, perhaps to help us survive. Accept your urges and thoughts of revenge as a basic human response related to trust.
Trust is important in any relationship and critical for cooperative societies. When you are thinking about revenge, it usually means you believe trust has been broken. Remember, while the anticipation of revenge may feel pleasurable, the actual carrying out of revenge brings little satisfaction and may create more problems and suffering. Acts of revenge do not repair trust or restablish a sense of justice for both parties.”

I know it isn’t good for me,sometimes though…lol
It is often bad for us!
Yes! Even when something bad happens to them of their own accord. I still feel terrible for them, I hate being nice,lol
