I think the fact that to Elon Musk the morals of this are confusing to him, says a lot about who he really is.

Or rather confirms what many may have already expected for a while.

Russia started an unprovoked war against a peaceful neighbor. Ukraine is defending themselves, while Russia can end this instantly, by merely going home. How can Musk doubt the Ukrainians right to defend themselves?

As I see it, he can only do that by having no empathy or sense of morality, something he has shown in many situations now.

Also the escalation thing is a very clear Russian and Putin talking point. Russia call it Ukrainian escalation even if Russia did the same 10 times worse. The only escalation of this conflict is 100% due to Russia being the aggressor and their continued aggression.
