Question about Arnos (vol 8)

If I'm not mistaken, in the fight against Graham, Anos felt a huge desire to kill Graham, despite claiming that he wasn't hating Graham (which I'm not sure if it's true), he had a huge desire to kill Graham and while he smiled saying he was very happy that Graham turned out to be such a horrible person, as it gave Anos the perception that he could kill him at will without giving importance to anything else.

After Anos finishes Graham, he tries to avoid looking at Sasha and Misha's faces, I could be wrong, but I believe Anos was trying to avoid showing his face in such a "dark" moment of his? As if he didn't want them to be afraid of him because of this "other" somewhat "psychopathic" side of him?
