It was a huge miscalculation. Even Russians that hate Putin are not going to be comfortable with support for a coup from a private military.

Peter Zeihan stated the obvious in a video on this that Wagner would have been decimated from the air on their way to Moscow too. I don't think you need to attend an Army war college to figure that out.

Ultimately, someone crazy enough to build a giant private army is going to do crazy things.

None of this seems good to me unless one is cheering for the doomsday clock to strike midnight.
