If my thoughts are correct, offspring of evil - no matter how old - can be healed. Noone should cast the first stone.
Assuming that a part of the evil is connected to blood & genes, an alteration of the biology would be conducted along with the betterment of our (political & social) environment and an according education.
If what we asume to know from scripture (we only have parts with the bible, which were altered by translation and for the purpose of control) it would concern us all. I don't know anything of my forebearers more than three generations back, not even sure of those I know.
Tiptoeing on this topic, not knowing past or future. Maybe science fiction, but I imagine therapies way beyond.
The least we can do is ajust our thinking to that possibility. Isn't that what we received free will for?
health, blessings and love anon
