To me, the larger issue for the world outside of Russia is the ensuing chaos would be pretty scary when there are nukes sitting around. All it would take is one bad actor to get ahold of those for bad things to happen. I don't think it's likely and I can't currently see the motivations for using nukes on any other nations apart from Russia itself and Ukraine, but chaos is chaos and many would consider the evil we know to be safer than whatever else lurks around the corner.

Personally, though, despite being aware of this it would regardless please me so much to see Putin fall. I would especially love to see Russia democratize more, but I'm afraid that's probably a pipe dream anytime soon. Uncontrolled chaos generally doesn't lend itself to more democracy.
