Not true. They have no emtions because they, as Nobodies, lack a heart. Besides, not all the Nobodies in the organization necessarily gave their humanity willingly to turn to darkness. Sora certainly didn't intend to turn to darkness when he freed Kairi's heart and created Roxas, did he?

The decision was their choice. We know that at least Ansem's apprentices were morally deficient even before they lost their emotions, as evidenced by their experiments, so it's not as though they were the nicest people in the world even before they became Heartless.
Again, I'm going to have to point out that we only know that five of the organization members seperated their bodies and hearts on purpose and we know how Roxas was created. We don't know how the other seven became nobodies. They could have been nice people. Roxas was a bit of a jerk before his memory was wiped, and he came from Sora who was a genuinely nice guy. For all we know, the person who Saïx came from could have been the kindest person you'd ever meet.

Ok, the apprentices may have originally thought their research would benefit everyone, but their Nobodies (save Axel) never thought about anyone except themselves, and they were willing to hurt anyone in order to complete their goals.
Of course Axel isn't included. He wasn't one of the five apprentices.

The two Organization members I feel sorry for are Saïx and Axel. They were the only members who expressed the desire to have a heart for the sake of having a heart. Everyone else either didn't say a whole lot about it, or they were like Xemnas who only wanted the power of a heart. Actually, most of them seemed to be having a heck of a good time being Nobodies.
