Sophocles’ Ajax. After Achilles’ death he loses a competition for his armor to Odysseus, who has bribed the judges. So Ajax goes insane in his rage and kills a bunch of livestock thinking they are the other Greek leaders. When he returns to his senses and realizes what he has done, he kills himself in shame.

It’s all about sophrosyne—moderation, proodence, emotional self-control.

Well, yes, in the Iliad he’s the epitome of strength, but he’s also the guy whose opinion other soldiers respect the most, and, sadly, always second-best.
