"Does your Corpse Child have the Assassin adult backstory"
- Yes.

"...does it have the Psychopath trait?""
- It did. I began the game with 3 corpses nearby. Sent the Psycho Child to consume one of them and it removed his Psychopath trait. He became a "companion", from 123 P's. He then consumed another corpse to steal the Hard-Working trait, and turned the third into a CC, who was also negatively affected by the Ideology's precept, despite having the Psycho trait.

"Is it getting these thoughts when doing the corpse children harvesting, regular surgical harvesting, or something else?"
- Corpse Children harvesting. I have not done any other sort yet.

"Is the pawn/corpse being harvested part of the colony, a prisoner, an enemy, or is it any pawn/corpse?"
- Slave/Wild-Man/Pilgrim(?) corpse that started nearby from the scenario editor.

If you wish to have a look at my game rq I can test stuff as per your advice, just tag me in RW's official Discord. Do you think I should bring this to 123 P's attention as well?

I still had the first save of this game, from when they just landed on the planet, before consuming any corpses. I went to save my game so I could load this one and test it out, but managed to save on top of it, replacing the damn save. Yes, I'm stupid.
