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
His father did regret at the end but Etienne already lost his trust towards him
And just because he is his father, he did treat him better at the last few chapters
If I'm Etienne, I will never forgive him
He never did what a father should do
He never protect his own son
And he didn't even realize that his son can die anytime, thanks to his 'wife'
Same. While I understand the father was a victim of the empress, I prob would just want to never see the father if I'm Etienne. Too many painful childhood memories.
