Hell is such an incredibly primitive concept, devised from a primitive society who's idea of justice is simply revenge. Revenge really has no purpose other than indulging our urge to inflict harm upon others, to gratify our own urge to inflict suffering upon those who inflicted suffering. The real means to end suffering is not to create more, you'd think that would be a no brainer. To meet undesired suffering with more suffering, is like trying to put out a fire with a flamethrower...meanwhile still trying to figure out why the forests are burning.

I personally believe evil should be viewed as a disease, not an enemy. You don't eliminate cancer by trying to inflict pain on it, you eliminate it by careful reasoning to find the most efficient means of eliminating it. Hell is completely pointless, an existence that creates unbearable suffering which would only set in motion more suffering by karmic means. A logical god would simply blink irreversible evil out of existence.
