What I also think is cool is that by the end of the manga most of the FMA characters had replaced the various sins they were driven by with Greed
but the constructive kind of greed- greed for a better world.
Greed even directly calls Winry “someone who wants it all” after she’s dealt with her wrath- she’s replaced it with a desire to have what she wants and a confidence she and the people around her can achieve it. And Ed and Al eventually do the same. And of course Ling and co are all about that too.
