Anyone else notice the MASSIVE Death Flag that Armin triggered? It's not terribly uncommon in stories such as this for the author to foreshadow a character's oncoming demise by having a heart-warming scene featuring said character (this is amplified in Armin's case, as he and Eren make a promise to visit all of the wonders the outside world has to offer after they retake the Wall).

Also, having the Beast Titan, who has hardly appeared since his introduction, kill Armin, a main character who has been present since the first chapter of the series, would be the perfect way to remind readers just how dangerous he is, and it would be the perfect catalyst to send both Eren and Mikasa over the edge.
