Roy and Riza's journey in Fullmetal Alchemist is the struggle of the naive idealism of youth against the cynical realism of adulthood. At the core of their characters there is a tenet: that Alchemy — or rather power — should be used for the benefit of the people. Like many things in FMA there is an irony in this. This belief that's so crucial to their characters is something they inherited from someone who, in a way, represents the antithesis of this idea.
Berthold Hawkeye.
The Manga goes out of its way to tell us this is something Behold believed in and passed on to them. First when Roy uses it to justify why he joined the military, and then when Riza admits that she believed in her father's words.
The thing is that there is a dissonance between Berthold's teachings and his character's actions. Berthold is a recluse living away from the people his hoarded knowledge is supposed to help. Roy and Riza know this, and they call him out on it.
They both fervently believe in Berthold's teaching, and they don't understand why he's so adamantly against putting it to practice. When they join the military they don't do so to spite him, they do so because they believe in what he preaches, so much so that they want to prove his cynicism wrong.
The problem is that Berthold is right.
He's sooo freaking right.
Their government is corrupt. All that talk about protecting their people is pure propaganda. His cynicism is the pain of someone who was burned too much by the world's cruelty. Berthold is an idealist that has given up, much like Hohenheim before Trisha. He is someone that once wished to help people, and probably came to the same painful realization that Roy and Riza eventually had in Ishval. The path to hell can be paved with good intentions, and sometimes you're completely powerless to do anything about it.
Now, what makes Riza and Roy such great characters, is the fact that instead of falling into despair and secluding themselves like Berthold did, they decide to fight back and continue clawing at the world with their own — no longer so naive — idealism. They have seen where defeat leads to, and they refuse to walk that path.
My favorite example of Roy's acceptance of both Berthold's teaching, as well as his rejection of Berthold's character, is his conversation with Hughes in Ishval.
This conversation is such a beautiful call back to Berthold telling Roy that alchemists die when they cease to think. This is Roy doubling down, acknowledging that yes he was naive — the world is a much more complicated and painful place than he realized — but still he refuses to give up on the face of reality like Berthold did. Where Berthold accepted his fate, as a man who was already dead inside, Roy and Riza continue to struggle to survive.
Berthold might have taught Roy and Riza that power should be used for good, but his biggest lesson to them was perhaps serving as an example of what happens when you allow your dreams and hope to die.
Ps. This thematic of children following on their parent/mentor footsteps and surpassing them is constant on FMA. Winry being a mechanic like her grandma and deciding to be like her parents by forgiving Scar. Ed and Al becoming alchemist like Hohenheim, but also embracing their familiar bonds and continue to help people despite their trauma. Ling Yao becoming emperor and dismantling the infighting his father had promoted. Scar embracing his brother's alchemy and dream. It is then fitting that Roy and Riza also inherited something from Berthold and then surpassed him.
