Yeah you're probably right. The GM can or has as much to do with the culture as the HC. If Hue was undermined by personnel decisions, which seems to be the case, isn't it possible he was undermined in other aspects?
I once was assigned to a unit in Germany that was overly lax. Hands in your pocket type of thing. Squad leaders, Platoon Sgts etc all were tasked to get jobs done with little support from our Beer guzzling First Sgt (GM). In comes First Sgt Thomas and over f'ing night things changed. Suddenly the chain of command worked and became incredibly fair and efficient.
So imo a f'd up FO can ruin the entire culture. Not sure if we can judge Hue accurately in that environment.
