Are you joking
Example like
Luffy got sprit broken by ace and want to quit the pirate life. Jinbe who is non coc help luffy to get his will power back.
Boa hancock- have to keep her secret from public. She can just I use to be slave to CD but no more I am free woman to public. That is strong willpower/spirit.
Chinjao - Garp is bully and Chinjao got sprit broken by Garp punch.
Kadio: Got oden pstd amd now crazy about oden guy. If kadio is strong spirit, he would not be worried about oden stuff when zoro bring Emma sword on him.
Kidd is deserve to have coc will power, but he is like Tom like Tom and jerry show.
Sengoku - is literally follow the order from gorsei. But he is more stressful guy like law when come to the plan stuff. But it is bad example or sprit broken but not good example of strong sprit.
Maybe I got wrong word of sprit break wrong. More like not strong will power when still have coc thing.
If IM have coc thing, I will call IM the biggest coward in the universe, he is hiding to rule the world and I would never talk bad about super paper Mario bowser ever again.
