I disbelieve in the fiery abode of eternal damnation stuff primarily because I don't hold much stock in the sources from whence it came/developed from.
Also, the more sinister and fear-mongering in nature, the less serious I take it - the more obvious it seems as a tool for submission/assimilation into an awkward, unnatural, unhealthy, foreign ideology. It is conveniently attached to value systems, theology, etc. in stark contrast to my own as well...which makes it an even harder sell of the product being pitched. The basis of marketing is to create or exaggerate problems and present the best, greatest, etc. solution/s. You have to put some faith in the marketer/seller or really put it through its paces. In every way possible, the fiery abode of eternal damnation falls short for me.
