Johannes de Silentio (Kierkegaard) selects Agamemnon as the ideal example of a tragic hero. Like Abraham, Agamemnon had to sacrifice a beloved child—his daughter, Iphigenia. However, Agamemnon doesn’t have to do this as a sign of faith, but to appease an angry goddess. It’s also for the greater good because other people will benefit from the sacrifice and will praise Agamemnon for being strong enough to make it. This is also what differentiates a tragic hero from a knight of faith: the tragic hero is universally understood and praised, but a knight of faith is nearly always misunderstood, and their actions seem questionable.
