One thing i like about Sougo is how Sorachi contrasts him with characters like Kamui and Nobume. Both Kamui and Nobume insisted that Sougo is the same as them, that he’s a fellow killer.
But we’re shown time to time that that’s not the case (to all 3 of them). No matter how cruel, sadistic, and a spoiled little brat he may come off as, he has a good heart deep down. And that’s all because of the guidance he received from Mitsuba, Hijikata and Kondo.
