Wolverine’s healing factor

How do you stop someone who seems able to heal any and all wounds? It’s simple – you remove his ability to heal. This has played an important part in various X-Men storylines, including 2013’s The Wolverine. James Mangold opted to use this trick again, this time to much better effect.

That’s because Logan addressed other issues that accompanied the failing healing factor – how could the body withstand adamantium poisoning? Furthermore, how could Logan use his claws without becoming infected each time he unsheathed them?

So his death at the end of the movie made sense. Yeah, he did survive an atomic blast. But his healing factor was failing him, so being impaled by a tree was all it took.
