Homicidal tendencies weren't what I was getting at, but that'd be a rather obvious possibility for most people. Violence (and a few of the characters here and in canon could seriously use a bitch-slapping of epic proportions) usually stems from anger, but I was talking about a sense of apathy or numbness.

I've seen plenty of people break (worked in Health Care). If they don't off themselves from whatever pressures or problems, it's usually 'Que Sera, Sera' for a while.
