I really hope the mc stops with this pacifist bs he has in some cases (though i think he did kill those guards in a earlier chapter), these guys have literally been cruxifying men, women and children and your supposed to show mercy?
There's not killing because of morality and then there's not killing due to stupidity in a story, at this point killing these guys would SAVE more lives than ruin others, sometimes killing is the best solution. if you don't like making them suffer your strong enough to give them a quick death, but come on man.
@feha
I doubt he's actually dead, though he might be close (more excuse for the mc to use his super magic, though he'd need to get them outside first), if he is dead, they essentially ruined the entire point of the last few chapters while also making a pointless plot point for drama.
