41 Then he shall say to them also that shall be on his left hand: Depart from me, you cursed, into everlasting fire which was prepared for the devil and his angels. (St. Matthew 25)
Your question is tough. Let’s see if I can give it perspective.
Yahweh God being Omniscient, Omnipotent, and Omnipresent, Knows that man will fail, right from the onset of Creation… Choices follow:
a) Do not Create man
b) Create and re-Create man billions of times till he get himself right
c) Create man as an automaton (no will, no cognizant ability, no capacity for failure or for holding a thought…)
d) Create man with a built-in excuse (no consequences for sin/anti-God)
Would God not have been limited in His Creation if all that would be Created were creatures and things that could not have the ability to aspire to unite themselves to their Creator?
Would man have gained anything in an un-Created state?
Now, why hell?
St. Matthew’s passage is quite clear: created for Satan and his angels.
Let’s go to Creation… what happens at the end of the Creative period? God Saw that it (Creation) was good.
So why not just kill the evil/bad seed?
Well Ezekiel 18 has a depiction of God’s Reasoning: Even if a man is wicked his child can choose to align him/herself to God.
Jesus gave us a window into this conundrum:
28 And he said to them: An enemy hath done this. And the servants said to him: Wilt thou that we go and gather it up? 29 And he said: No, lest perhaps gathering up the cockle, you root up the wheat also together with it. 30 Suffer both to grow until the harvest, and in the time of the harvest I will say to the reapers: Gather up first the cockle, and bind it into bundles to burn, but the wheat gather ye into my barn. (St. Matthew 13)
So God suffers the wicked so as to have Mercy on those who would willingly turn to Him.
Your proposition… do you truly believe that if there were no consequences to sin/immorality that man would turn from wickedness… look at the contraception technology… when it was introduced and accepted in the secular world, even “Christians” embraced it; the Pope warned against it… soon divorce became the next thing that was embraced, then abortion… millions of children losing their lives in their mom’s wombs and millions more being victims of divorce, and millions embracing adultery and fornication… and millions suffering from all sorts of stds–the false premise of liberation through contraception has not worked!
Imagine if you will an after life where no sin/immorality prevents humanity from entering Heaven, how many millions/billions would not embrace destruction and the destruction of others since there would be no eternal consequences?
Finally, consider the various destructive behavior that man engages (as aids or the opioids use/abuse) with full knowledge that engaging such behavior places his life/existence in jeopardy… is God’s Way not better: He Creates us and patiently allows us to Choose Life: Christ?
Maran atha!
