I would take it better if he dies at the end, after they accomplished their goal. I thought they gonna kill him off at the very end and let him enjoy "the place where they belong" just for a split second before he died.
Also the luck and the bias of screen writer on the bad guys is way too apparent, the bad guys escape major death twice by absolute chance and not to mention survive scot-free after got blown by bomb, stabbed by giant sword (this happen way too many times) and literally survive after becoming vegetable. We in the fandom call this screen writer's plot armor.
The screen wrtier of this series is a sadist
