Wow, some people need English lessons.
No they didn't....... nobodies =/= organization 13.
Even knowing what you do now about the whole "organization wanting to be whole" thing? I have yet to get a good response on why trying to get a heart is a bad thing.

Even though I don't personally agree with the methods of the organization, i can't justify sora's acts of genocidal rage against them. The thing is that we don't know what is going through the minds of the organization, only of sora, so we don't know what has happened to them to make them do what they did. Sora, being a semi-rational being should have thought to put himself in at least one orgs members shoes before it was too late....
