Why isn't Putin receiving the same level of hate than people like Trump and Elon are?

I’d argue it’s an objectively true statement that, of all the people alive today, Putin has singlehandedly caused more death and suffering than anyone else. The gap between him and whoever is second is likely orders of magnitude. Yet, when I read discussions about him, Russia, or the war in Ukraine, I almost never see the kind of hateful, nasty, and mean comments directed at him that I regularly see aimed at Trump, Elon, or even ordinary Republican politicians. Why is that?

Bonus question: Why be so nasty about it in the first place? There’s nothing wrong with criticism, but I struggle to understand the need for such meanness. Even when I agree with the sentiment, reading comments like that feels toxic. It poisons my mind too. I don’t like being angry, and I avoid it for practical reasons as well. Anger clouds my judgment, and I think it does the same for others and thus should be avoided.
