Stampedes are apparently a regular event, so it's negligent to not have made efforts to bolster defense, or simply not continued to expand the village and gone elsewhere less dangerous. If ogres regularly cause great amounts of damage each time, sturdier walls being built seems prudent, but they did little to none of those if his first response was worry the walls will fall. She's not entirely pulling things from nowhere.
