The video opens by questioning whether Batman should kill the Joker, introducing Batman's Kantian adherence to a strict no-killing rule. This is contrasted with the ongoing harm the Joker inflicts, raising a moral dilemma about responsibility when one has the power to stop a killer.
Kantianism, based on an absolute moral rulebook, is explained. Utilitarianism is introduced as an alternative, focusing on the consequences of actions rather than intentions. Founded by Jeremy Bentham and John Stuart Mill, it posits that actions should be measured by the happiness or pleasure they produce, aiming for the greatest good for the greatest number.
Utilitarianism is presented as a hedonistic but other-regarding theory, meaning it seeks to maximize pleasure not only for oneself but for as many sentient beings as possible, encapsulated by the 'principle of utility.' It encourages making moral decisions from a benevolent, disinterested spectator position to ensure fairness and unbiased judgment.
Bernard Williams' thought experiment is used to challenge utilitarianism: Jim is offered the choice to kill one indigenous person to save 19, or refuse and let all 20 die. Utilitarianism would demand Jim kill one, despite the moral discomfort, highlighting the theory's demanding nature.
Act utilitarianism, the classical form, dictates choosing the action that produces the greatest good for the greatest number in any given situation. This is illustrated with the 'Organ Harvest' dilemma, where an act utilitarian might justify killing one healthy person to save five needing organ transplants.
Rule utilitarianism is introduced as a refinement, suggesting that we should live by rules that, in general, lead to the greatest good for the greatest number. This approach considers long-term societal utility, arguing against actions like organ harvesting even if they maximize short-term utility, to avoid a society living in fear.
