It's called "cheating" for a reason.
Suppose I decided to start calling people on the phone and telling them that they owe money to the IRS. I'd say, "There's an officer outside your house waiting to arrest you if you don't pay me over the phone right now." It's a classic scam. It is also called "cheating."
I might argue that while it doesn't leave me morally clean it's something I can live with. To me, the alternative is way worse. The trouble is, my victims may not be able to live with what I have done to them. But, who cares? As long as it's the better alternative for me, right?
Fortunately, A person who does that will spend some substantial time in prison if he is caught, which may discourage many people from trying. Unfortunately, there are no legal consequences for those who cheat their spouses, which is why it's easy to dismiss one's guilt with a verbal acknowledgement that it is a moral transgression while continuing to transgress.
If I needed to employ someone of good character, do you think you would be a suitable choice?
