One possibility is that Yanukovich is more humane than putin or lukashenko. I don't know enough about him to compare but the last two are merciless dictators.
That's not a real possibility though, the only way Ukraine will be kept down will be with continuous threats. I personally don't think he will live an hour after he sets foot into Kyiv.
There's another thing that was different at Euromaidan vs current Russia: Yanukovich and his people had somewhere to run (Russia). Putin doesn't.
He doesn't have to run to someplace, he can just run into some stuff. Preferably a bullet.
Compare the total area of Ukraine and Russia - and max distance between the border and the capital city.
