mary being brainwashed in s12 and sam's soullessness in s6 serve a very similar anxiety - the fear isn't just that an outside force is making them this way but rather that this is who they truly are, someone they've always been. even if its not their fault, dean still blames them for their actions during this time bc the arcs are supposed to highlight a "Wrongness" that already existed in sam and mary, exacerbated by these conditions
