No, the reticence was to do with poor command structures, abysmal logistics, and 19 year olds being sent over the border without really being told what their objective was or why they were there. Putin has already cashiered the head of the Russian army. He expected this to be a cakewalk, and it hasn't been.
NATO may not intervene directly (which would be a tragic mistake, too) but NATO countries and the EU have been a lot more resolute than most expected. After all ten days ago if you'd said that a Russian invasion of Ukraine would lead to enormous economic sanctions, the indefinite pausing / bankruptcy of Nordstream, supplies of military hardware and civilian aid from around the EU & neighbouring states, Putin careesers being publicly shamed (Gerhard Schröder's entire private staff resigned from under him today), SWIFT deconnection, that a fast track EU membership for Ukraine would not only be discussed but actually put in motion, you'd probably have been thought pretty mad, naive, or both. Yet, here we are.
All of this is of little consolation to folk currently hiding in basements from Mariupol to Kharkiv, I understand. But it is a lot, lot more than could have been expected prior to 24 February- and a lot quicker, by comparison with the international community's sluggish and inept handling of the Bosnian War during 1992-95, let alone the abysmal indifference to Afghanistan, Syria, Palestine, Yemen, & co.
Another thing: Putin is absolutely indifferent to indivdual human life. The ordinary Russian citizen is about as important to him, as an individual grain of sand on the local beach is to us. He's a friendless,greedy sociopath and if there's to be a world without a powerful Russia, according to his perspective, then why have a world at all? He will be more than happy to see Russia's great cities in ashes if he can profit from what's left of the world after.
