Those kind of questions can not be made without context, it is not a game of words without consequences. If it is a game, just to waste time posting in this or any social network, let’s stop here.
It is about a real person, who is a leader, whose murder would spark grave consequences. And that leader actions, like taking the decision of going to war or not, are related to decisions made by other leaders. Right now there is a campaign demonizing that leader, and that campaign normalizes ideas mirrored by that kind of questions. There lots of memes, jokes and things like that asking for Putin’s dead.
If i asked, what would happen if Donald Trump were assassinated? Or Biden, or Xi Jing Pin, Erdogan, etc? At this moment when all media are strugling to influence public opinion? It won’t be a futile harmless game.
