4. Craster
On the subject of progeny, that old swine Craster's shenanigans earn him a high spot on this list. As I mentioned earlier, he isn't the most likeable of fellows. What I didn't mention was that this is largely due to the fact that he has incestuous relations with his own numerous daughters, who live in fear of him. Incidentally, he doesn't appear to have any sons, which is quite odd for a man who has around 20 daughters (I'm guessing) with whom he routinely procreates. There's a good reason for that. One night during the Night Watchmen's stay at Craster's Keep, Jon Snow spies the old scoundrel making his way deep into the woods. Naturally, he follows him, and watches as Craster stops to deposit a package on the ground. As he turns to make his journey back home, Jon hides from view behind a tree in the shadows. Suddenly, the cries of an infant can clearly be heard; Jon wastes no time in unsheathing his sword and legging it in the direction of the sound. He has enough time to discern a humanoid figure as it picks the child up before Craster knocks him out cold. Later, having regained consciousness, Jon reports what he saw to the Old Bear. Much to his disbelief, the Commander already knows about Craster's sacrifices to the white walkers. According to him, they are a necessary evil so as to keep the creatures placated. Do the ends really justify the means, though?
