Temporary release of adrenaline would only be satisfying to someone who feels gratification in doing wrong to others. If you let it go, "This too shall pass". I would rather feel I had done the right thing because only I have to live with the consequences of what I do to others. My conscience would be bothered if I did that to someone and I am the only one who has to live with that conscience. Treating others good regardless of what they do to you is a sign of a good inner character, not a vengeful one.

Do unto others, as you would have them do unto You. It does not matter how a person treats you, just treat them good.
