Babies are more pure and studies have shown that as one ages, their blood becomes less pure/contaminated by life choices/diseases etc. These terrible people have done studies to transfer baby or young person's blood to adults [adult becomes healthier/younger] and adult blood to babies [these became sick and or died]. Babies and young persons are innocent and therefor more reactive to terror, producing more of what is considered high quality adrenalin. Abortion is so horrible in many ways. I hope your theory isn't true. My thought is that a soul [a person] is the combination of spirit and physical body. Tho the body is damaged and dies, the spirit rests/returns to Source/Eternal Great Spirit who I think of as All LoveAll WisdomAll Power and that is why people say 'rest in peace'. and 'No more pain or sorrow' when someone [still a person, now simply a spiritual entity] leaves their physical body. But yes I also believe there are entities/spirits that are adversarial, that are in error/damaged/ungodly and energetically thrive on acts of distress, aggression and purposefully torturing, killing, maiming. I see indications that people that attack others also experience adrenalin release and if they have no love, good grounding or desire to self control, may become addicted to their own adrenalin releases.
