No no no no, nothing so UNsubtle.

Its more like.......

I'll give an example.

Suppose baddamanna has OCD. He'll tell him "Something is wrong.", then let him be.

THEN, in EVERY room, he'll shift something that is in plain sight, yet unnoticeable to the CONSCIOUS mind, to an unnatural position, driving said person mad.

Also, yes. If his intricate strategy failed, "BEAM THE NUKES IN." or "RAM THAT ASTEROID DOWN THEIR SUCTION HOLES"
