Would rape really make more sense tho? Or could it be ppl are so used to it happening in manga they feel that's the logical outcome even tho it might not be? A question to ask ourselves.

Of course it would make sense. Because the younger brother dies want bis brother in thst way and seems crazy. And I only gave examples of what would make more sense. A lot of things could have happened, but what happened makes no sense at all.
It's got nothing to do with "getting used to it", it's about the facto that thise two aren't in good terms. Both are mentally out of it, so there's no way you could fix this by just talking a little.
The Characters' behavior makes no sense to me at all.
I thought there would be some really dark, psychological plot development, in which the older brother maybe tries to kill himself, or gets raped by the younger one. All of that in addition to a plot that leads there and from there onwards, would have been a lot more reasonable.
At least, that's what I think. And no, this isn't about me preferring darker plots. And yes, this seemed to be a plotline that I particularly love, but it's also not about that not happening.
This is solely based in the fact that the first two chapters indicate a story that just isn't meant for an outcome like that. It's illogical, though it starts pretty good.
