Trauma bonding with a ham sandwich and a glass of warm milk

Trauma bonding is a where you take two people (I suppose it would work on a larger scale) and put them through a terrible traumatic experience. The terror of the experience makes them like each other. Say you take three people, kill one of them. The remaining two will be much closer then if you had not killed the middle guy. Sharing the common experience of horror brings the remaining people together. Creating commonality where none previously existed. This can be used to integrate an outsider into a close nit group that normally wouldn't tolerate an outsider. It can be used by intel agencies to get an agent into the trust circle of the 'bad guys'.

Rape. Torture. Murder. Pain. Take your pick.

Oh yeah, you suck. You suck hard.
