I agree with the first two. But he is not a fair representation of the Empire. To suggest that he is would be to suggest that every Amarrian is a deranged, genocidal monster—and you and I both know that’s not true.
He is a product of his environment, yes. But there’s a certain quality that a person has to have in order to make the leap from “scoundrel with low tolerance and little regard for human lives” to “complete maniac with no ability to empathize or care about the damage he does to societies.” Most Amarrians—and most people in general—lack that quality.
Not every Empire loyalist would pull off the carnage that’s been seen at Gamdis, or any other such atrocity he’s masterminded. And that’s why, instead of being the height of the bell curve, he’s way to the left of it.
