In my games it is quite rare. The few times it has happened, has always been when someone was deliberately lowering their humanity on the journey to a path, and made the mistake of committing diablerie when they had almost no humanity left. It's actually been kind of a funny "oh crap!" moment. I did ask if they were sure they wanted to commit diablerie. That's usually a big clue from an ST.
How often has it happened in your games and under what circumstances?
