Apart from terrible things which happen to people I know, nothing, I really don't care. I watched the IS video of the Jordanian pilot being burned alive and it was just whatever to me.
I'm not edge-lording and morally it's utterly repugnant and if I could have taken action to save him (without being killed myself) I would have done so, but I don't get how people get so shocked at things which don't affect them personally.
