To not believe in eternal torment does not imply any "sympathy" for the devil or for evil of any kind.
I believe that eternal torment is simply not what the Bible teaches. I do not deny there is a "hell"; I simply do not believe that it is populated by eternally living persons. There are all sorts of arguments for the position I hold, many of them directly appealing to the scriptures themselves; in other words, even though I find the notion of eternal torment incompatible with the notion of a loving God, I don't think the scriptures endorse such a position in the first place.
