Hi guys I'm looking for fics where John or Dean kill Sam either on accident (i.e. a car crash) or on purpose (can't save him), they don't even have to be the ones to do it, but they should be directly responsible for it in some way (i.e. sending him out unprepared for a hunt, driving him to suicide) . Whether Sam comes back or not is fine, really I just want massive amounts of angst.

Wincest or gen is fine, pre-series would be amazing.

Thanks!
