Actually, God did and does “bother”. He came into the world, Jesus is his Name among us, and he sacrificed his life to his Father, to enable us to have the life of resurrection from the dead in eternal happiness. That is why we bother, not being better than God, but being LIKE him, like our Father.
That is the Official Good News (Gospel) that the Catholic Church is announcing to you, Bahman, that God has established his Kingdom, with himself as our King, sacrificing himself for us and rising from death to make us alive also. And it is for you, too, that he came. Jesus is also your King, having done what he does to lead you to faith and hope in him.
In the resurrection we will not relate to people the way we do here, and we have a hint at what that means when Jesus says, “In the resurrection they neither marry nor are given in marriage”. Marriage at his time was a means of financial security for retirement and old age. But in heaven, there will be no anxiety about future good or evil. We will know provision of all good from our King, our God. And when we see those in Hell, we will see goodness all around them, yet they see it as fire and do not want it. They only want to sin but have no place to hide and sin, no satisfaction, even though all around them is goodness from God. And how can we be fully happy while seeing this? Because we see God not doing violence to them, forcing them to trust him when they do not want to, ever. When they see us, they will not envy us, as if they wanted the same happiness they see us having, but will think we are fools, settling for God when we could have sin. Someone in Hell will not look at us and see a loved one, because they have no love in them, only unsatisfied desires, hungers, lusts, and impossible schemes for satisfying their own desires. And you will see this, see them as they really are. You will not see with sentimentality of what “might have been”, but see what really is.
