Paisen is such a bro, i wish he had real friends, maybe now that Tobio is being honest with himself and to others (at least to Paisen), they will be able to make a real bond.
Paisen acting like a real adult for once. I guess manga in the end is teaching us to know how to truly move on despite such past crimes. the suicidal thoughts being a good thing as proof of being alive. Morally even with 10 deaths (regardless if those guys are pieces of shit or not) and them not getting the deserved punishments (especially Maru) I have mixed feelings but story-wise this is pretty solid.
