In my opinion he's scared. He's dug a hole he can't dig himself out of because he's surrounded himself with yes men who tell him everything is fine and seemingly, that the Ukraine "military operation" would be a walk in the park. He's completely miscalculated the West's response, he was not prepared for the sanctions and the fact that theft of state resources under his rule has, on the back of it left the country in tatters. He has no end game because he can't occupy Ukraine. Russia is huge and he'll have to quell insurgencies all over the place, from potential breakaway states who now know the Army is useless.
Almost all Dictators in history go the same way - ultimately ending up in a position where keeping power is the only option, by whatever means and they get more and more desperate.
Fortunately, they usually end up on fire in a ditch when those around them realise they need to do what they have to in the interests of self-preservation. I think it's significant the Oligarchs are speaking out. That suggests they're not scared. Abramovich even flew into Moscow earlier this week.
