Remember his question and speech early on in the series (paraphrasing a bit here):

"What do we do here?" General confusion, Dedra quotes from the ISB handbook and is told WRONG

"You want security? Call the Navy, launch a regiment of troopers. We are healthcare providers, we treat sickness. We identify symptoms. We locate germs whether they arise from within or have come from outside. The longer we wait to identify a disorder, the harder it is to treat the disease."

He has no illusions as to what his job is, and is clearly comfortable with the idea of dehumanizing any and all potential dissidents of the empire's order. He is a professional at crushing opposition to a totalitarian regime and knows it, takes pride in it even. Whether he maintains some semblance of workplace comradery or not, whether he thinks Ghorman was a bad idea or not, is a moot point. He even says security is an illusion, that's not his goal, to him some people are simply not people. Merely germs to be cleansed, a disease to be eradicated. So, I would say objectively not a good person.
