After skimming through raws until ch20, think it's better to not getting translation. Another one of those shitty mc
with no kill policy where he lets enemies go, and then they just return safely and make better preparation to harm mc's companions, demon lords of this era. And he says he wants to keep them safe, hypocrite . So far, nobody died yet since he saves them right before bad guys kill them after toying with them, very conveniently waiting for MC to come .
yeah i was thinking about that while reading the chapter, i can only think of violence to put a stop to that policy, he must bring down those in power, it was pretty weird for me to see him not killing them when they were about to capture torture then kill someone, i can go around it since it's the first time but if he keeps being that way even in the future i'm not sure i'll like it, making a country or place for others demon lords works too by making sure people understand that they shouldn't mess with but ultimately violence and blood is inevitable to make that point, if they slowly make the populace also understand that they just want to live in peace it might work well to put an end to the policy.
if mc is too op he can also just straight up go and meet the ones who can put and end to the policy with some talk with power showcase
