Being in an Iraqi prison and having your head clamped to a little metal thing that they turn that gets tighter and tighter, then watching your family be tortured raped one by one, then they cut you open with knives and slowly tighten the clamp until your head collapses in.
I think that would be the worst way to go, knowing that almost everyone you loved died because of something you did and then having knife wounds while your head is being slowly crushed.
