Honestly, trying to figure out Sora's kill count is pretty confusing. Specifically regarding Xehanort.

Like, do all the Xehanort forms count as one guy, or separately? Do we count only the first time they were killed, or do all subsequent defeats also require a tally mark? Is Sora legally responsible for death by old age, death by Kingdom Hearts door, or time travel shenanigans?

And then there's whether or not Castle Oblivion events need to be considered, whether the Datascape needs to be considered, or whether the Sleeping Worlds need to be considered…

Fuck, no wonder Donald tells him not to meddle in other worlds. This shit gets confusing.

But totally average for a Squeenix protag.
