Winry and Miles are basically the first two to break the cycle of hatred! They could've easily went down the same path as Scar with hate and vengeance consuming them, but they didn't let that happen. I love it! It was a nice contrast to see, and I love how we can see their actions and words affecting Scar and it's making him reflect on everything as a result.
What Al had to say to Zampano and Jerso was beautiful!
