I understand, but sin is misery. It is greater punishment ‘fulfilled’ than not.
Sin separates us from God, which is the greatest existential suffering we can imagine, which is what the definition of hell is.
In Dante’s Hell, each sinner received what sin he wished, for eternity.
Yes, but the thought (plan) of committing any sin is a sin in and of itself. Temptation isn't sin, but evil desire is. I think what MLG was postulating was that evil desire in a reprobate is a given. Consequently, what makes hell "hellish" is that none of those desires will be satisfied. This is as contrasted with on earth, wherein many times the sin is satisfied.

If they were damned anyway, why would this be worse? :)
