1-It doesn't matter at all whether the Grimm learn or not. The point is, we've been told before that they personally destroy mankind's creations from time to time, even when there aren't any humans around.

So to see not 1, not 2, but 3 villages which are far more like Ghost Towns than actual ruined villages, it's inconsistent and disapointing. I would understand focusing on the humans first, but it doesn't excuse not wrecking at least part of the place to a noticeable extent.

2-"Sense of safety"? Only a complete and utter moron would think a Ghost Town overrun by nature and decay would be a safe place.

Besides, there are myriads of Grimm. Even if some of them decided not to bother wrecking the place, it doesn't excuse the N other Grimm, especially the young ones who rush blindly towards anyone.
