And in the FF world exist far more strange things than "cyberarms". Actually it is really, really strange enough, that we/they can't heal his arm. While we may not cure death (probably because the "essence of life" leaves the body), we for sure heal a lot of broken bones, filleted organs and crushed, burned, corroded (and so on) bodies. To heal a cut off arm seems almost simple in comparison. But sure, the drama...
I guess growing some thing back is more difficult than healing something still there maybe?
