The former is Karl Willigut, Nazi occultist and member of Heinrich HImmler’s staff.
The latter is mass murderer and soul harvester Gary Ridgeway, known as the “Green River Killer” after the river in Washington where he dumped the bodies of his victims. Like many mass murders, Ridgeway preyed on sex workers or “sinners” in line with religious traditions. What he was really doing, aware of it or not, is collecting souls to be brainwashed and used in future lifetimes for the political ambitions of a Controller. Again it’s a good idea to thoroughly read the wiki entries.
