Why does this surprise you? Russia just can't afford another Lenin during the war. Or another Yeltsin.
The last thing they need now is a fight for supremacy, similar to what we have in Ukraine, that would cripple their war effort and benefit only their enemies. The death or one of the opposition leaders may be considered as a small price to pay to avoid the 1917 like catastrophe. Today, with the abundance of nuclear weapons, the stakes for the whole world are much higher than then.
