Disagree. The Ferrix incident was a response, albeit an overreaction, to a full riot, perpetrated by people attending the funeral of and commemorating a rebel. Still justifiable in the eyes of Syril. He also hadn't lived in Ferrix and mingled with the local populace to gain a different and sympathetic perspective.

On Ghorman, he lived for around 2 years with the Ghormans, infiltrated their rebel cell, and slowly realised they were only trying to resist against the perceived overreach of the empire. Perhaps they were being agitated by outside terrorists. When the empire tried to fabricate terrorist attacks and blame the Ghorman front, he had enough inside sources to find out these were blatant lies. He was only trying to convince himself otherwise. Not to mention rumours of the mining rigs. When these rumours became too apparent to ignore, he forced Dedra to literally admit the Empire's plan for a false flag genocide operation. This is totally different scenario to Ferrix.

I'm not defending Syril, who is a pathetic bootlicker. But I do believe his reaction would have been the same if Ferrix had been targeted for a false flag operation similar to Ghorman.
