If he was a Buddhist monk, this is probably why he did it...
Desire is almost as defiling as the act itself, however: "He who enjoys looking at women, even in painting, is not detached from the act." In the traditional Buddhist classification, there are three passions: hatred, love, and ignorance. Desire, in the form of love (raga, a word meaning color, but also lewdness, concupiscence, lust, attraction), is therefore one of the "three poisons" that pollute and maintain human existence. According to this conception, all existence (human or nonhuman, because this is true even for the gods) is fundamentally defiled.
Guess he took care of the problem altogether.
Looks like he'll have to pee with a catheter thingy from now on.
