"Why I don't regret my abortion"

Evil people can come from loving families and have been well brought up by their parents. Human nature is not perfectible, and there can always people who have personality flaws that are no fault of the parents. And your scenario still relies on the family lineage never having a weak link which would cause someone else to be condemned to hell.  And of course, once one family member ends up in hell, does that mean that when the parents get to heaven, they are relieved of having any concern for the wellbeing of their progeny (otherwise if the torture of their son or daughter was preying on their mind constantly, that would hardly be heavenly, would it?)? Or does one bad apple condemn the entire orchard to hell, because the parent bears some responsibility for any sin committed by any of their descendants?




That's just a continuation of your justification for the parents taking a gamble with the eternal future of their progeny rather than aborting it and guaranteeing it a berth in heaven.
