Disturbance
You have got to be the highest magnitude of insanity to push someone over the edge, to provoke their anger on purpose, and to make them snap into a frantic episode of rage; so you can have a motive that would justify an excuse for you to physically harm them as soon as they try to retaliate. That is the cruelest most sickest prank anyone could ever pull on somebody else. A person's emotions is not to be played around with and there is nothing funny about dying or getting hurt. It's already bad enough that you're doing this because you shouldn't be doing it at all, but to do it every chance you get like it's a "full time" career is below the belt and overstepping the limit. If there were levels to being insane; you would be on the level that is above the toppest level. It is the point after the end of a particular point!! That's where you are on the insanity...
