Psycho-Pass
According to the anime world of Psycho-Pass, the future is run by a system called Sibyl. It dictates pretty much every facet of life, including whether a person is deemed likely to be a criminal. Akane Tsunemori is tasked with enacting Sibyl’s judgment on those people the system indicates as a threat, wrestling with the morality of jailing or killing candidates before they’ve actually done something wrong along the way. A story of right and wrong unfolds, oftentimes leading Akane to a gray area.
The moral ambiguity of Psycho-Pass is something that Tokyo Ghoul itself tackles throughout its narrative. Is hunting down ghouls who’ve done nothing wrong righteous, or is it unjust? Kaneki Ken attempts to answer this question himself as he exists as both a human and a ghoul, and must oftentimes decide who his true enemy really is. In some cases, Kaneki doesn’t have to right to choose between right and wrong in the first place (as in the chance with Psycho-Pass’ omniscient Sibyl system).
