This is what I believe as well. Other than being a member of the clan, he had no skin in the game. This was all JW and AW(custody) and GW3 (Chris Sr beef). I don't believe for a second he is innocent of anything.
They were an enmeshed family who planned and worked together. That's all GW4 needed to participate in the execution of 8 innocent members of the Rhoden family.
He stood by and helped kill innocent people while infants and small children were in the same rooms, the same beds as their parents, with no concern for their safety. Along with the rest of his murderous family, he left those infants alone with their dead parents for several hours.
That's not the kind of person to excuse or pity or seek to support, as some do. Like the other Wagners, GW4 should be locked up for life. He's a sick, twisted, violent person.
