[Phil The Balrog]

You know, i often wondered this same question. I would say that Hobbits are probably capable of evil, but certainly not predisposed to it. Almost like angels. In the Bible, the only bad angels were the ones that were led astray by Lucifer. There were no accounts of angels being bad on their own. Perhaps Hobbits have much the same nature, good unless led astray by the Ring or some such force.
