There is no stopping it — comic book villain Negan is going to kill a beloved “Walking Dead” character when the show returns for its seventh season. Although doom, gloom and blood is on the horizon, the cast of the hit AMC series seemingly wants fans to know that Negan actor Jeffrey Dean Morgan is a nice guy.

Devoted followers of the show have been waiting for Negan to arrive, and he finally made his first appearance on screen in the Season 6 finale. Of course, he wasn’t exactly welcoming to Rick (Andrew Lincoln) and his crew. In fact, the last episode of the season ended with him killing someone with his beloved barbed wire bat, Lucille. The Alexandria survivors had killed too many members of his group, The Saviors, and he needed to teach them a lesson. Viewers didn’t get to see who Negan chose as his victim, but the cause of death was undeniably vicious.

The villain is known in the comics for being completely ruthless. He has an extremely foul mouth — something that the show had to slightly tweak for broadcasting — and is known to be violent. Neighboring communities are required to hand over weapons and other supplies or pay the consequences. He even enforces strict rules inside his own group, using an iron to burn those who disobey him. Although “Walking Dead” viewers have yet to witness just how terrible things can get with Negan, the cast has been taking to social media to show their fan base that actor Jeffrey Dean Morgan is as pleasant as they get.

Prior to joining the cast of “The Walking Dead,” Negan appeared on “The Good Wife,” “Extant,” “Texas Rising” and “Grey’s Anatomy.” The actor told “Late Night” host Seth Meyers in January that his new role as the comic book villain is a “game changer.”

“It’s a complete 180 from what I’m doing on ‘The Good Wife,’ which, as an actor, is like a dream come true,” he explained. “I get to be the biggest a—in the world.”

Although some of it has to be dialed down for TV, Morgan recently confirmed to Entertainment Weekly that they’re shooting his dialogue two ways in order to get the best reaction from the other characters.

“I learn what’s okay for TV and then I learn the Negan way, which is nothing barred,” he revealed. “And I will add every f---, f---ing, f---edy f---, and more, just to f---ing get a reaction.”

“The Walking Dead” Season 7 will premiere on AMC on Sunday, Oct. 23.
