he was a massive asshole, he mass genocided a entire city, but he said "im sorry" so its all fine in the end i guess...
seriously, what the fuck is wrong with these people? after how he treated them and after what he has done, he himself chose this path, to become a demon, to mass genocide and burn down a entire city, they should cheer and celebrate his death, not be sad, there is something seriously wrong in the head of the author, this one chapter alone dropped the series from a 7 to a 3.
