Except there is different definitions for both psychopathy and sociopathy.I fail to see why you think his factual sociopathy is mutually exclusive with taking a liking to specific people. That's not how the disorder works.
Good point, but I think it's more related with priorities and values in life, rather with psychical disorders. Sort of the trolley problem.Reminder this is the guy who canonically tried to bust Kallen out of her scheduled execution by letting loose a pile of Honkai beasties (from Schiksal's containement pens - at the time they didn't have the means to destroy them and has to settle for capture) to rampage on the town as a distraction and was quite genuinely confused when the lady was hella pissed at him for it; chronologically this was while Vera/Octavia was still alive, too.
