After all, it's written for the Japanese who must already attend a prep school to clear the entrance exam to a reputable kindergarten. It only gets worse after that. When they are finished with the education system, they enter the workforce forcing them to do 14 hours days and attend obligatory drinking parties, where the main point is to lick their seniors boots. If a Japanese dude gets married and gets a family, he will hardly ever get a chance to spend time with the children, and the wife is in total control of all family finances. And pretty much everything else at home. With life like that, they certainly dream of getting hit by Truck-kun and getting isekaied into a paradise that's exactly as challenging as they ever would want it to be and not a millimeter more.
Edgelord revenge stories are a different thing. They are written for bullied people, which Japan is full of. The point is to share the experience of common suffering, so the MC may undergo brutal torture and worse, and then finally kill all the villains.
Of course there are a few expections also in isekai. This series ain't one of them.
