Is there something about the word *torment* that escapes you?
I’m sure there will be the mental, emotional, spiritual torment of regret, but Scripture is quite clear that there’s physical torment as well. The rich man who was in hell said he was in agony (anguish) in the flame and asked for a drop of water to cool his tongue. That sounds like torment to me.
2 Peter 2:4
For if God did not spare angels when they sinned, but sent them to hell, putting them into gloomy dungeons to be held for judgment;
Hell here seems to consist of dungeons.
