If it went down that route he would’ve given into the dangerous side of being a half elf. He prob won’t kill this guy either for the same reason. he is acting with restraint to not lose himself. It was stated she was going to turn him into a man earlier in the series. Not sure what is too confusing.

yea, I'm sure it's done a lot, but not doing it can be predictable and maybe even less climactic as well. The trick is how it's handled... like im sure the cliché would be he goes evil and is brought back and the day is saved.... *yawn!* lol but maybe it ends with him being evil... (probably not)
Regardless the twins are kinda going to be a bane for him in my opinion considering they most likely wont have any aptitude. I wont count them out entirely considering his foster parent's family kept books so clearly they were not normal slaves... but keeping books around is more ingenious than being gifted or talented.
im all kinds of conflicted... there's the nefarious events going on that leads to a lewd scene... then the MC's shounen powers activating at the end for an "alls well that ends well" scene.
I feel conflicted because the scenes don't match well in my opinion. It's lewd in juxtaposition to justice. Honestly I kinda think it would've been more drastic for the twins to be sold, … uhhh etc etc.. (I don't wanna think what he would've done to them) and killed them and have the MC even more tormented then have the teacher come in and be like... we were wrong, which would have drive him more mad in contrast to him just being beaten and abused
tl;dr if they're gonna go with this twist of him becoming a failure I would've gone for the jugular... I mean I thought the twins would've been sold before he returned home.
