First, a man cannot kill the army. There is just ONE sword but many walkers. If they are smart enough to move into just two packs, there is a guaranteed masacare and more walkers.

2. North is a very wide and harsh land. By the wall, it's frozen and snowing even in the winter and almost nothing grows. For first men, they had no reason to wander snow to anihilate the walkers and Childrens, just to get wasteland.

3.  it is impossible to anihilate walkers because anyone who die outside of the wall, even though they are not killed by walkers, becomes walkers. One may forbid men from leaving/entering the wall but no one can forbid others from dying.
