I follow an infidelity blog and actually see a fair amount of this type of thing written about in the posts there - awful person cheats on their spouse, but maintains a great public image, and most people who become aware of how they treated their spouse will blame the victim, rather than look at the cheat’s behaviour. It feels like an injustice, and on some levels it is exactly that - they (cheating spouse/unethical T) seemingly get to go on like nothing happened, while at least one person is left suffering because of their actions.
