"Perfect hatred" reminds me of a commentary I was reading on Rev 14:9-11. It said the presence of the Lamb and the Holy Angels made their suffering more, "exquisite". 
It gets even worse (if that's possible). A Calvinist fellow told me how watching the damned for eternity will bring him so much joy and thankfulness that he is not among them.
All heart, eh?
are you SERIOUS?
And there's one worse. The same guy who told me this is all over the web (he goes by Beloved57). He also told me he will be laughing at the plight of the damned when he sees them in the fire (even if they happened to be his wife or kids) because it will be God's perfect justice and reward being accomplished. I won't repeat here what I told him about the condition of his heart

Think about it though. Arminians often argue that it would be cruel of God to force the bliss of heaven upon those who don't want it. On the other hand, they seek to DISTANCE themselves from it (the LOF) and claim they won't even
remember their lost loved ones ect.
My response is that if it is so merciful that God did not force His love upon them and so right and good of Him to place them in the eternal flame then why do they want nothing to do with it? Why
shouldn't they rejoice if it is the perfect goodness and just will of God (think about it).
It's because they KNOW it's unconscionable, to which they often respond that they have just that silly human empathy which God lacks.
Then I show them that if they are with God, and Jesus, they will witness the LOF

Most don't like to hear about that part....
