True enough. He's like a Stalin in the making, without the communist ideology. And with the killing of potential opponents happening on a smaller scale, but in a more spectacular way (having them poisoned with plenty news coverage rather than just having them taken to the backyard and shot without further ceremony)
I read an interesting article yesterday, where parallels between Putin and Stalin were made and a major difference was why they felt a need to undermine the idea of an Ukrainian nation. Under Stalin, you had the more-or-less planned starvation catastrophe called the Holodomor, and you had mass deportations of Ukrainians to Siberia. With Putin's rule happening in a time where Ukraine is, in fact, an independent country, I guess he's doing all he can with the annexation of Crimea, the destabilization of Donbas and now the invasion.
