How bad is cheating on a scale of 1-10 if 10 is the worst thing possible?

A lot of people cheat. Does that make it not that bad? I think it's really bad still but I want to see what you all think. No judgment here. For this poll's purpose, cheating is when sex happens with someone else and you know it would break someone's heart.

Please don't select 10 though unless you really think it's just as bad as the worst possible things like torturing someone in a demented way and eventually killing.
