If an eternal hell existed, it is God's choice to send people to hell and his choice alone, not their choice. Nobody says "I choose & want to suffer endless torments in hell, please send me there, God." God could be merciful & save them from such an unbelievably horrific & sadistic future by simply annihilating them out of existence. Then God wouldn't have to send anyone to "hell" let alone an endless hellish existence of torments. So your doctrine of God makes Him into a sicko sadistic monster worse than all the serial killers of history combined.
Moreover, God could choose to send unrepentant sinners to another place rather than that "hell" (the fiery lake) of endless torments. For example, He could send them somewhere where they wouldn't be allowed to harm anyone else & where they could spend eternity enjoying pleasures much like they did while alive on earth.
So even under the assumption that God chooses to send people to an endless lake of fire to be tormented forever based on how they lived during a brief lifetime, that choice is on God, not human beings. Because God had at least 3 alternatives to sending anyone to endless sufferings in hell. In addition to the two i stated above, He could have sent the unrepentant to a "hell" where they are corrected & eventually saved so they may join others in heaven. To fail to do so implies your God's love has an expiry date like a carton of milk or He is impotent to save (so He is not Omnipotent as Scripture says), or He doesn't want to save those in "hell", in which case He is not loving or good but a sicko sadistic monster.
Furthermore to bring endless sufferings on anyone for the relatively momentary sins of a lifetime is extremely unjust. Additionally, it is also pointless. Is it supposed to bring God glory or illicit praise from the saints in heaven. Quite the opposite.
It's the idea that God will cast anyone off forever that the inspired Scriptures, in their original languages (not English), correctly translated & interpreted, do not teach.
Lamentations 3:22 and 3:31-33, The steadfast love of the Lord NEVER ceases, his mercies NEVER come to an end. . . .
Lam.3:31 For the Lord will NOT cast off FOR EVER:
32 For if He causes grief, Then He will have compassion According to His abundant lovingkindness. 33 For He does not afflict willingly Or grieve the SONS OF MEN.…
