I'm surprised that crazy director is his first kill after all that berserkers he went through
But oh well, I just remembered that he really did never kill anyone, neither in his consciousness state nor his berserker state
He just hurt them until they can't recover at that time and only others continue killing the people he injured just like his teacher did to that crazy researcher in the beginning
Nah, the emotional manipulation threw me off
i did support the human and MC, but the way he use his injury to make MC stay by his side is quite mehhh
