Ngl this is my biggest issue with this version of this story. If you're going by the light novel or the manga you're kind of going along with the story with the notion that the MC is just evil for evils sake. Like he's motivated by misplaced curiosity, boredom, and in this particular part, bloodlust. The build up to the coup works because he spends all of it in the background testing his powers and trying to see how far he can go. In those versions it's clear that his whole motivation for this was to see how strong he was by fighting the commander and the massacre of everyone else was just because he had an excuse to somethinghe wanted to do anyways (even tho he gave a later justification to cover his tracks)
Here tho he really had no reason kill anyone past the people after the second princess. She was as good as dead and if he wanted to he could have passed her off as such and kept his word to help her escape. He's so much more mild mannered in this version that none of his insane actions make sense for the setting anymore and I just don't enjoy this version as much as I thought I would because of that.
This just seems…unnecessary, I actually kind of wished he was in one of those other worlds that he first got summoned into. They most likely would have been more interesting.
Even the coup, it was necessary, the royalty and nobles were draining the life out of the peasants. He and the other heros should have ran away from the beginning instead of getting involved. I actually didn’t like that he killed the new king because he actually wanted to fix the country and help the poor. The MC would have not given a shit had he not suddenly found affection for the first princess. Also the country is now royally fucked because both sides have killed off most of the knights. So now all that can really defend the kingdom is whoever’s left. They honestly should have minded their own business and let the country sort themselves out. Take the princess with you if you want, but get the heck outta there.
I was shocked but I didn’t develope any feelings for the royals to actually care about their deaths. But honestly his last summons was the worst, so maybe the author should have chose another setting to make it more interesting.
