The Walking Dead has killed off its fair share of characters over the years, with the brutal death of Glenn at the hands of Negan being one of the most memorable and bloody events in the comic's almost 200-issue run. Being the one responsible for all the death and dismemberment that takes place on the page, The Walking Dead’s creator, Robert Kirkman, has revealed that despite all the harrowing situations he puts his characters through, their deaths affect him almost as much as if they were real people.
