Do you realise the guys who post stuff like that want people to be triggered?
Dark humour is a great thing but it has no limits, I remember watching stand up comedies that were just taking the piss out of 9/11 not even that long after it happened, it isn't for the faint of heart in anyway.
But considering we live in a world where people get triggered and salty about someone sending 'prayers' to someone, i'd say whoever posted this is sat there smiling like a Cheshire cat at the level of troll.
