LET'S GET BACK ON THE POINT.
Yes, let's. This talk of judges and juries and the death penalty is making my eyes hurt.
Situation as I understand it:
-Relationship that is exclusive (based on individual describing his extra-relationshippy actions as "cheating")
-Cheats on SO after big fight
-Cheats on SO again after another big fight
-Takes steps to conceal his cheating from SO
If I'm the SO, I will eventually find out. I would end the relationship. And here's why:
-Cheating as a response to a fight in a relationship demonstrates a lack of maturity that I could not live with
-Cheating repeatedly demonstrates a lack of willingness to learn more appropriate responses to a fight in a relationship
-Lying about it and trying to conceal your cheating ways demonstrates you want to have your cake and eat it too, without regard for my feelings or my sexual and emotional health.
-By seeking another's sexual comfort in a time of stress, you've betrayed our bond, on multiple occasions, and I am not confident that I can trust you any longer.
IMO, there are degrees of cheat and betrayal - the response above reflects this singular case alone.
