I was trying to remember where I have seen that technique used well, and it occurred to me that this conversation in Episode 5 of
Code Geass is similar:
Timestamp: 14:35-16:03
The two boys speaking are childhood friends...who have been on opposite sides of two different wars, both flipping sides between childhood and their teen years. They have very similar reasons for wanting to fight, but *very* different outlooks. In this conversation, they lay out their reasons for fighting...but also reveal why they are never going to see things the same way. Naturally, they will be opponents throughout most of the series. They both want to end war to protect the weak...but one is going to conquer the world as a supervillain to do so
