"Commander Fox was wrong" this... "Commander Fox did nothing wrong" that...
Commander Fox was an enslaved man who acted as the leader of a fascist police force. He did everything in his power to do things the right way, but he was also extremely loyal and directly under the thumb of THE Darth Sidious at almost every moment. He and the majority of his force were heavily isolated from other clones on a day-to-day basis. Anakin had so much more independence and support, and even he became evil under Sidious's influence. Other clones in strictly controlled roles later chose to defect regardless of their position. We never got to see Fox's face in spite of him being one of the more significant commanders. He died quietly at the hand of Vader.
Fox's situation is beyond unprecedented. Because he's always in this oppressive environment, we never get to see who he is beneath the armor. There are no Jedi to know him on a deeper level, no people for him to fight for, no room to breathe. He has no agency, and his role is to constantly stomp on the agency of others.
Commander Fox is one of the most interesting clones we never fully get to know. Almost everyone oversimplifies who he is as a character or changes him fundamentally when using him in fan works. He deserves better from Star Wars fans and official writers alike. I will die on this hill.
