Take a close look at Matt 10:28 God is the one who "Destroys BOTH body AND soul in fiery hell" according to the Bible.
So while it is true that the Rev 14:10 fact of "tormented in fire and brimstone" is a Bible fact that can never be sidestepped -- yet as we see in Matt 10:28 the end of that terrible process is to "destroy both body and soul" in eternal fire. A destruction that is fully capable of "destroying them by reducing them to ashes" as Peter tells us when speaking of other examples where God has destroyed by eternal fire.

Having said that -- take a look at Romans 2:13-16 regarding the case of "non-believers". People without access to the Bible. Because God sends His Holy Spirit to "Convict the WORLD of sin and righteousness and judgment" there are according to Romans 2 -- some non-believers who though they have no Bible at all - are being lead by the Holy Spirit and will be accounted as informed-Bible saints while many Christians who DO have Bibles and knowledge of the gospel will be counted as pagans.
