When you meet Edward Elric he gives off the impression that he's the short-tempered hot-headed "violence is the answer to all life's questions" kind of protagonist, and it's in fact incredible character craft that he's actually the character who ends the series with a negative-3 kill count.

God's worst soldier Edward Elric. Showed up as the youngest member of the Amestrian army, took millions of dollars from them, never followed a single order, helped dismantle their fascist regime, left with a lower kill count than he arrived with, then fucked off to go be a house-husband. Character of all time.

You know, when you said "negative-3 kill count," I, who haven't seen the anime, thought, "He resurrected 3 people?????" But I'm seeing here on the wiki that apparently resurrection in this anime is a terrible idea.
