We start our Faith as an empty shell. Remember before we start that nothing we can do on our own merit alone will gain us our last end, heaven. We cannot even avoid sin without the grace of God. Grace is a quantitive gift in that sense and what we merit and strive for is grace.
We start by taking the initiative in prayer, following the commandments, being humble, thinking of others before self, and following the obligations of the Church. This makes the Father take notice in us, we are selected to warrant a certain quantity of grace. WE act first and wait and trust and hope.
Now as we progress God gives us the grace of moving us away from a fear of God to a love of God. Our Faith is advanced only through the will of God. As we progress in Faith, more in spiritual personal revelation will be made known to us and self contentment is experienced, and we will come to realize things that we were uncertain of.
If I understand you correctly you are refering to things that happen to people. These things are temporal opportunities for us
to act, and they may be unplanned calamities such has weather or the result of the compounding of someone’s sin, ie: a family left destitute because the breadwinner was murdered, or deformities of newborns,abortions, tc,etc. If we notice something horrible happening, the thought that should form is “what can I do here”, not “why doesn’t someone do something here”.
Hell is a place that is the opposite of heaven in every way, and logically follows from a precept that maximum all Good of a loving Father must also exist a place where there is an absolute maximum absence of it. No one goes there unless they want it. Those who are not qualified for heaven have chosen to go there, as there is nowhere else except purgatory which is a cleansing place for those destined for heaven. Purgatory was made for temporary stay only.
The aborted aren’t burned in hell. God’s merciful love for children
ensures us that unBaptised children although kept from the beatific vision of God are destined to an eternity of contentment and natural happiness.(most theologicaly accepted).
A mother carrying a child and gravely ill and not assured of her future can ask someone, or simply request Christ baptise her child by desire and the child is accepted. If born, being his representative, all she needs is to baptise him by water and he is accepted. There is every opportunity for someone to care for a child who is destined for heaven and take the appropriate action.
I see God as one who does not act with ill intent, but withholds according to what we desire. If we desire evil then that measure of evil counters that measure of grace we possess and cannot reside in the void with evil. So if you have “n” amount of grace and choose an evil, then you are discredited by “n-1” amount of grace equivalent to the seriousness that God is offended, and that allows more evil to fill that void. This is a simplistic way of putting it, but it helps formulate a concept. If mortal sin, then one is scratched off the “destined for heaven” list, and every good he does is not credited to him until the offender receives the sacrament of Penance, then all the credited good is restored and he is once again entered on the list.
Christ is eternally happy. He chooses to suffer along with us now in our afflictions and ordeals before his second coming and promised to be with us until then and stand by his Church helping us through it by the Sacraments he provides. But when that comes the elect will be eternally happy along with him and all suffering will end.
Hope this helps.
