Speculations I don't think Kizaru will ****

[meeta]

I don't think Kizaru will betray Saturn in the traditional sense. Meaning that I don't think he will turn on Saturn straight up.

I think Kizaru might help the Strawhats once he has been beaten by Luffy and sees the true hearts of both Luffy and Saturn during their inevitable battle.

Maybe Kizaru will have a moment which parallels Kuzans from Ohara, or maybe Kizaru will defend Bonney after having a sudden change of heart.

Kizarus justice is unclear, and I don't suspect he knows I suspect he doesn't know what he will do before the moment arrives.

sees the true hearts of both Nika and Saturn

This is not a romance manga

Absolute nothing indicates Kizaru changing.

Kizaru will lose to luffy just like he did at the middle of the arc.

Saturn is the biggest threat here since we have no idea how far does his regeneration goes, what's the use of cutting him in half or bajrang gunning his body if he can just regenerate again.
