Exactly. Most of them are brainwashed. And it's just gonna get worse. Russia is out of the picture for decades to come.
Most are on the path of least resistance, not asking many questions as long as life is ~comfortable, or at least not getting dramatically worse. They kind of like the strongman. And there is always alcohol/drugs.
Added: In general I agree with varjag's assessment. The average Russian family supports Putin.
I have little faith that Russian society is going to come out of this war any better. It's a cultural thing. Germany had to be razed to the ground by am external force and millions of Germans had to be killed for the society to ditch militarism. And Russia has nukes.
We can't know without better introspection and data to ground the discussion.
