We're probably at the point where a lot of the Hatsushiba old guard is going to start dropping in the next few years. Oizumi's probably going sooner rather than later given that he never 100% recovered from his own stroke, Mangame is in his 60s I think and even Fukuda is looking pretty old now.
Although whatever they may think of Nakazawa's wife, taking his funeral to publicly embarass her is a pretty shitty action. Especially given that from her perspective he was a philanderer who seemed to not really care about his actual family... which is pretty much the case. That and even if they did it coldly, taking him off life support instead of living as a vegetable was objectively the right and humane call. Especially as her own Christian beliefs could have easily meant that she just leave him (which would also have been punishing him for his actions).
