He's not as bad as John Luther in that sense; he's sort of broken, and I do feel for the guy. And while Patrick is a walking stressor, Luther oscillates between "breaks the law in violent ways to help innocents" to "breaks the law in violent ways to help himself." But Patrick's grating and insulting in counterproductive ways, and although he gets away with it because he's helpful and, well, the protagonist, I don't have a lot of sympathy for people who are impolite just because they can.
Most of them well-off white male geniuses, unsurprisingly. (Luther is a not well-off black male genius who regularly abuses whatever modicum of power he has legitimately earned through his being good at his job, which makes things more complex, Elba's great acting aside)
Insert here the obvious comment about the World's Greatest Well-off White Male Genius Who's Unnecessarily Irritating To People He Works With, Bruce Wayne, whose overall plan vis a vis the JLA seems to be they think of themselves as good people, so the more they personally want to kill me because they find me obnoxious, the less likely they are to attack me even when technically they would have the right to, or maybe just the newbies don't kill me because they think I'm tough enough to mouth off to the Clark, Diana, and J'onn with impunity, and Clark, Diana, and J'onn don't kill me because they are genuinely good and extremely patient people whose personal lines I've spent a lot of time profiling to make sure I never cross.
