I believe that Hell, being the absence of God’s presence, would be so much worse than what the aborted little ones went through. Remember, Jesus in the Garden, sweating blood. Not because of a fear of death, but the stress of being separated from His Father for the only time in Eternity. I cannot imagine how terrible Hell would be. As another poster mentioned, remember Luke 16:23.
I agree with you, it is much worse than what the baby went through for the baby ended suffering with death, his suffering began at death and never ends.
