@Maki @shuuya24 what we know is about what happened is:
- Some time ago there was a war between every gang out there.
- The war was escalating and got out of hand (cripples, deads, people "disappearing", targeting families, gay blackmail...)
- In that war, Kilihito's 5th gen head, Jou, was considered the most dangerous, brutal and the principal cause of the war.
- The other gangs and Kilihito's 6th gen wanted to stop the war and EVERYONE agreed that taking out Jou was the only option.
- The 6th gen overtook the 5th gen.
- The 7th didnt agree with what the 6th gen did, so they frammed them which ended with them being sent to juvie.
Both gens betrayed their higher ups, something that goes against the most basic rule in a gang: dont turn against your elders. But the 6th gen did it to stop a war, with all other gangs approving it, while the 7th gen did it just for revenge. Thats why the 6th gen wasnt isolated after the war ended while the 7th gen is isolated by every other gang and some of them joined the 6th gen as soon as they got out: because the 7th gen is in the wrong.
This isnt about who is better or worse, is about who is in the right or in the wrong by the rules they decided to play. They are delinquents and they play by their rules, where doing messed up things isnt "wrong" in their eyes, but "normal". Jou was fucked up, Nikaku was fucked up and there are a lot of other fucked up people in all three generations because they just take what fucked up people do as granted. But even between delinquents there are limits and Jou crossed them all, so someone got to take care of him.
