First, if anyone is in hell, they are not truly loving anyone, and never did. Their character has been about themselves, not about loving any and all people the way Jesus wants >
"if you love those who love you, what reward have you?" (in Matthew 5:46)
So, they do not and will not have the character which makes them able to benefit from being in Heaven. Because of their character >
"Destruction and misery are in their ways;
.And the way of peace they have not known."
. . . . . . . . . . . . . . (Romans 3:16-17)
Because of their character, they can not love and submit to God in His peace (Colossians 3:15), can not love as His family (Ephesians 4:31-32), and ones of this character became able to curse their own children with the shed blood of Christ > Matthew 27:25. So, they are merciless, by character, no matter how many humanitarian gestures they decorate themselves with. So, in case any are my "loved ones", they are not nice people, to say the least.
Plus, the character of sin makes a person deeply sick and weak so he or she can suffer the deep misery of sin, including how worry is so abusive and lies in very cruel ways about what will and will not and could and could not happen. I remember how I was; it was horrible. And in my selfish nature I was only or mainly concerned about myself.
So, I mean misery in which a person is mainly concerned about one's own self. And ones can tend to seek pleasures and excitements, in order to keep themselves from feeling the horribleness of their own selfish character. But as they keep desperately seeking nice feelings, they are exercising their deep weakness so they get "worse and worse, deceiving and being deceived" (in 2 Timothy 3:13).
And later in hell, that deep weakness will still be there > after there will be no more physical creation which they can use to try to feel pleasure. They will have nothing but their own selves, how they have become . . . weak so they can suffer torment.
So, we are doing what we can, now, to reach people so they join with Jesus and have His strength so we not only avoid the horribleness of Satanic cruel stuff in us, but also we share with God as His family.
Loved ones will not be in hell unless God knows they have Satan's character. Of course, then, they will not be evaluated by how charming they might have acted in this world, so we could fall in love with them and use them for pleasures; their real character is developing and will come out.
But if they refuse, they will get pickled in a permanent state. And if they were to be able to cry out from hell and beg us to save them . . . it will be coming from their character which had Satan considering Heaven to be horrible so he tried to destroy how Heaven is. Now is their time, then, to change and desire genuine salvation, not merely to use trickery to try to feel nicer while staying deeply weak.
So, how Satan would have Heaven would be horrible, and how they would relate with Heaven would be horrible; their horrible character is their dictator of how they can see and feel about things. And Jesus of Heaven has already come to minister for people to escape that, plus to share with God as His family, instead.
