How can you be perfectly happy in Heaven if you know that some of your family and friends, whom you love very dearly, are being eternally tormented by the flames of hell?
(This is a very weighty topic, and it may help you to watch this video of a Jordanian Pilot being burned by ISIS, and gauge your reaction towards a stranger feeling just seconds of hell, before answering hastily and carelessly

OPTION 1
You will be so enthralled by the tantalizing pleasure of being with God, that you will stop caring about the suffering of others. The enjoyment gained from being with God will completely annul the sorrow and empathy for your family/friends who are lingering in incomprehensible anguish.
(The downside of this theory is that it seems to be centered wholly on selfishness, you ignore the suffering of others because you are enjoying something amazing; an idea antithetical to the Christian ideal.)
OPTION 2
You will become so enraptured by God, and so moved by the desire for his interests that you will actually rejoice as you see the torture of sinners who did not obey God, even if those people are your own children, parents, wife, or husband. Seeing what you believe is justice which honors God, will give you more happiness than seeing your family members saved from infernal torment.
(The downside of this theory, which indeed was held by many Protestants in the 15th-19th centuries, is that it appeals to our senses as downright cruel and frightening. It also exhibits the action of betrayal, an action that is not noble, in that one “betrays” his love for his earthly family, and instead rejoices at their painful and never-ending agony.)
OPTION 3
Some part of your mind will be erased and you will no longer retain any memories of your loved ones and family members; their very existence will be wiped from your mind.
(The downside of this theory is that it appears to make humans playthings for God, who brain-wipes them against their will, in some sense making them slaves/robots).
OPTION 4
Your mind will be “reprogrammed” and all the emotion and feelings that you now have towards earthly loved ones will extracted, and then redirected towards members of your heavenly family. Simply put, God will take away your feelings towards your loved ones.
