"Letting" yourself degenerate to this point implies that you understand "this point" and that you're degenerating to it. That can't be acceptable to someone in a civilized society. If you understand it, then it's infinitely worse than if you degenerate to this point without understanding it. In any case, people like this cannot be tolerated. As much as some would like to be tolerant, understanding, or whatever, they're living in denial if they can't take someone like this and snuff him out. Comfort has its expense.
