Is a revenge affair just as bad too?

Lets say they cheated first slightly over a year ago, they expressed remorse about it and you guys tried working it out but later on you found it overwhelming. Initially you thought you could handle it but nope, you can't. The triggers don't go away.

Then you decide it's enough and want to break up but before that, you cheated back with a close friends with benefit you liked in the past. You did for two reasons, you liked them but at the same time it was for revenge too. You're about to break up soon. Now are you just as bad too?

Does this makes the former cheated on (now officially a cheater) just as bad too?
