These folks aren't interested in killing titans in the least, are they? In the beginning Eren was, but now he's just a coward and a fool to boot. Even when the female abnormal was being eaten, they suddenly stopped killing the titans even though it was the best situation imaginable: The titans were all in a circle, facing inward, totally oblivious to any attacks from the outside. If they had slaughtered them, they could have also potentially caught the human inside, trying to flee the scene. But no, since they have no intention whatsoever to kill titans (not counting when it's hopeless to attack, which is when they gleefully throw their lives away, like earlier against the still free abnormal). Even the ones guarding the forest borders were only concerned about sitting on their hands when perfect opportunities were right in front of their eyes. As a result there was a huge crowd of titans ready to storm the forest at a moment's notice. Naturally none among them, not even Armin, had the wits to realise how dangerous that is.

Now I remember why I eventually stopped reading the manga: This story is just too forced.
