You have heard the saying that God loves the sinner but hates the sin, right!
Although I have read once that God referred to certain people that they were already damned. I think those are the people that no one prays for and God who knows all things, knows these people will never cooperate with His grace, although He has already given them enough to save their souls. Knowing they will not cooperate He leaves them to their damnation.
Because if He continues to grace them, knowing anyway they will not cooperate, they will fall even deeper into Hell, therefore He shows them mercy, sparing them of the deepest parts of Hell.
That does not mean He does not love them, after all He died for them, as He suffered and died for you and I. He would have suffered the same for them, if they were the only people created, I was taught.
Also keep in mind in the garden of olives just before His crucifixion He saw the souls of every person created, and wept for the many He realized would not be saved. This was one of His greatest sufferings, as was His mothers. Although Mary did not see personally the souls of all the people, she just knew many would be lost, while her son still suffered for them.
The Bible does say that He favors some over others somewhere in the Bible, I know its there I read it.
