Not to show off my uber history knowledge but Phillip Of Macedon - a bad boy in every way - was killed by a man he raped during Phillip’s marriage banquet to his second wife who was already pregnant.
I wrote that badly. At Phillip’s marriage party, a drunk Phillip raped a paige boy/young man while Phillip’s henchmen held the victim down. This man later revenged himself by killing Phillip - probably in a plot Phillip’s first wife Olympia hatched up.
When the incident became widely known, Attalus, who was a courtier and exercised a good deal of influence with the king, invited Pausanias to dinner, and, filling with vast quantities of unmixed wine, handed his body over to his stablemen to abuse sexually in drunken rape. On sobering up from his intoxication, he [Pausanias] was extremely bitter about the physical abuse he had suffered and accused Attalus before the king. Philip, though incensed at the enormity of Attalus' transgression, was nevertheless unwilling to show his abhorrence because of his kinship with him and his present need of his services [3]. [...]
Accordingly, the king, wishing to appease Pausanias' justified anger at what had been done to him, conferred on him valuable gifts and promoted him to a more honorable position among the bodyguards.

They played pretty rough back then.
