Guilt can make people go insane. I really don’t think something like this is far-fetched at all, even in the real world. It’s amazing how the story proceeded and ended, I felt like there was nothing else that could’ve been done better. That aside, saying that he “deserved” it is definitely over-exaggerating, but the younger brother’s first thought was that his lover was “”taken away”” from him instead of his brother going rogue and might be having some mental problems with loneliness? Glad to see them all moving on though, this was an enjoyable read.
