Drugs? People use drugs for a plethora of reasons, usually to obtain some form of happiness. You know what hell isn't about, happiness. Sex? Yeah try having sex when demons or gobbling you up or stabbing you with pitchforks. Scientific Progress? What the duck?! I don't think petty human advances matter in the afterlife nor would they be applied. Rock and Roll? Never really thought rock and roll was strictly a "hell" thing. Lennon and Galileo? Assuming these two are in hell, what do you hope to accomplish if you meet them? Make small talk about the glories of music and mathematics while you are waiting to be pushed into the fire pits of eternal agony?
