For a supposedly unkillable mutant, the amount of times Wolverine has died is kind of ridiculous. Fans of the man they call Logan have already seen multiple Wolverine deaths in comics and even on the big screen, but time and again he returns to the pages of Marvel Comics.
In between those brief flirtations with the afterlife, Wolverine kills indiscriminately and is no stranger to absorbing all manner of physical punishment. His mutant healing factor is a convenient plot device for any writer who wants to unleash horrific acts of violence on the character.
Wolverine is the best at what he does, and what he does is suffer gruesome injuries.
