There’s also plenty of evidence that says that Russia isn’t doing so well, they have 100s of people in some battalions refusing to fight (likely because all their friends turned back up home dead).

There’s tonnes of HIMARS strikes taking out command and control points of Russias behind the front line. The VDV (Russian paratroopers) and it’s leader ship have been decimated by this war.

I don't doubt that some of their guys dodged conscription. In every war, someone does.

But "losing the morale war" would probably manifest itself in localized frontline collapses, and this does not seem to be happening. The recent retreat in Luhansk oblast wasn't a rout, and other sections of the frontline are barely moving.
