>>50815206Hypno fic where a trainer mind controls people with his Pokémon to get his way.
However, he becomes paranoid that he himself is being controlled, and double checks his motivation, memories, and personality constantly. The more he takes advantage of people, the more skilled and subtle he becomes at brainwashing, and the more paranoid he becomes. He uses this paranoia and potential lack of free will as justification to commit escalating acts of violence and sex, and the stress slowly drives him over the edge.
It's never made clear whether he's actually being controlled or not.
