In their moral justification, the argument of the lesser evil has played a prominent role. If you are confronted with two evils, thus the argument runs, it is your duty to opt for the lesser one, whereas it is irresponsible to refuse to choose altogether. […] Politically, the weakness of the argument has always been that those who choose the lesser evil forget very quickly that they chose evil.

Hannah Arendt (1906-1975) German-American philosopher, political theorist
