Yae aint tragic, but it is kinda depressing to think his fellow bullying classmates (who he admittedly didn't care for in his selfish life) completely scapegoat him for their actions when clearly they didn't care who started the bullying back then, they just wanted an excuse to elevate themselves over an ace student. Mind you, many of these guys admired him as a leader and then betray him to defend themselves from ridicule (and that is BEFORE they learned how evil he was compared to them that made him unworthy of respect).
Now with the bullying culture falling apart they try to weasel their way into Uichi's good graces cause its the "hip thing now" and they don't want to be isolated from their peers for being bullies. As Yotsuba says, they are bad people too, and I say they are just the ones that got away with it (to some extent). And to think these are the "better ones" compared to the middle school peers that just wanted to kill Uichi for sadism... What a twisted school enviornment.
