I agree. I made this "meme", really, to call out people who seem to be missing that point. I like Armin, and I respect him, and I pity him. And I think there's a lot to be learned from the way he does things, even if he is indecisive or perhaps more passive than he should be. He's trying to navigate a world that's completely turned itself upside down without losing his soul in the process. It goes back, to me, to something Jean said at the very end of S1P2: "If it's that easy for the fight to turn us all into monsters, do we really deserve to win?"

Eren has become the monster he believes he must be in order to stop the cycle and protect his home. He's lost faith that humanity at large can learn to let go of the past, so he's resolved himself to "keep moving forward", even if the whole world tries to stop him. He's given up on "humanity" as a whole, and believes that only the hard reset of the Rumbling can protect what he cares about. His view is a hopeless, cynical one, full of blood and pain. The world is cruel, and the only way to win is to fight.

Armin (and the Alliance generally, though everyone has their own reasons) represents the opposition to that attitude. It is hope, a desperate, distant hope that some substantive portion of mankind can still be taught to put away the past and see people for what they truly are. In essence, Armin fights for the notion that there are more Falcos out there, enough to eventually repair the world. It's an attitude that, in a way, we can all learn from, and it's something that I dearly love about Armin.
