Doing heinous but legal things in private isn't a get-out-of-consequences free card if your bad behavior gets exposed. If I discover my spouse is cheating on me, she can't say, "But I was doing it in secret so it doesn't count!" Well I guess should could say it, but most people wouldn't think that's a reasonable excuse.
