Sometimes, humour is the only way to get a message across. The world is so fucking grim at the moment (but I'm sure it will get better /s), humour is the only way many can connect. This is not poking fun at the victim, it's pointing out the aggressor.
Humor has always been used by the court jester to hide the truth and dissent in jokes. The OP meme would be even more funny if were Julian Assange among the dead in that round - but unfortunately he's still alive.
I mean, if it were DT, Kim Jung Un, Putin, Bibi, I'd laugh.
Might not be my proudest moment, but I'd laugh.
And if I had a time machine, Id be the one doing it to aspiring California governor and shitty actor Ronald Reagan. They'd never will have had found his forked tongue.
