I may not have Joseph’s wisdom, but I can attempt an answer:
There is really no correct answer, as it all depends on the circumstances. You clearly made the right decision given the information you had. If you would know ahead of time that the man would be forced to stand behind a scantily clad individual, then it would obviously be better for you to be the person standing ahead of him.
Whether or not he has “hearos” after that is completely his responsibility.
