Not to mention something I, as a SW fan, know better than anyone

The reason why so very few Space Wolves fall to chaos is two-fold

1: The Wulfen. It is clearly stated in the Codex that the Wulfen is, in fact, a response to Chaotic influence, as Chaos has a harder time corrupting non-sentient beings, such as the animal Wulfen

and 2: The Space Wolves are incredibly self sure. Selfdoubt is almost non-existant in the Space Wolves, something most Chaos Gods turn to when turning Astartes. The usual way of swaying an Astartes is if their squad are killed, but for the Space Wolves, a dead brother is as much something to be happy about as sad, because they have fallen like a warrior. And, since they believe in themselves to such an extent, it forms a shield of emotion to the temptations of the Warp.

And most of the 13th are Wulfen anyhow so :3
