Lmfao you've completely missed the mark on Kuzan.
Kuzan used to have passionate justice prior to Ohara, after Ohara the only time he ever showed passion was for the Fleet Admiral position. A position with by far the most influence in the Navy. When he couldn't get it, he couldn't stomach being in the CD bootlicker role for a single second longer, precisely because he's not a fraud.
I didn't miss any point, you said Kuzan is fighting for change and grouped him with Fujitora who as an admiral is causing not only internal marine change of ideology but also political change in the structure of the WG. Thus I asked where Kuzan was causing that change. Since he didn't do as an admiral...
He didn't show passion for the position of fleet admiral, he showed passion to not making Akainu the fleet admiral, two different concepts. Naively believing Akainu would give it up when Kuzan hadn't done anything of significant as an Admiral, while Sakazuki was actively an individual influencing things actively instead of being lazy... with Marineford making it evident who should lead the Marines.
After getting his ass kicked, he goes into depression and spends his days drinking. He then meets Teach, who brings some life into this man. Now with w.e goal he has in mind that we're unaware of, he empowers mass murderers.
@Bold, see how you had to create headcannon, that doesn't have a single manga panel supporting it, to make Kuzan look good? The fight was meant to be a death battle, Akainu let him live. You think any man with pride is going to stay in the same organization as the guy who not only crippled you but also showed you mercy when it was meant to be a death battle... a death battle that Kuzan started... like bruhz what??
