> there's been a tendency for Western liberals to concentrate on Putin, oppose him, and therefore idealize his opponents
Seems to depend on whether someone believes Russia's security interests have some level of legitimacy. If the war is unfounded then it is an act of madness and the motivation is probably attributable to a single charismatic individual (and Putin must be that person). The view is part of the "Russia's unprovoked attack on Ukraine!" narrative.
If Russian has legitimate security interests in the region then it doesn't matter so much who the president is and Putin's role in events is important but it is likely others would have made the same choice.
