In "Maveth," the midseason finale of "Agents of S.H.I.E.L.D.", Director Phil Coulson exacted his revenge on Grant Ward for the death of Rosalind Price and killed him during their interplanetary excursion. With a week left until the show returns, star Clark Gregg weighed Coulson's chances of going even darker and perhaps even becoming a super villain himself.

"One of the things I've always liked about Coulson and about our show is that he's a moral man," Gregg told TVGuide. "He's a normal man trying to do a job in a world with super villains and superheroes... and suddenly, the body count is piling up, as a result of Grant Ward, someone that he is -- to a certain extent -- responsible for having on this team. He crosses a very serious line, because he could have left him on this distant world and he chooses a different path."

"There are definitely people on his team who thought he should have pulled the plug on Ward a long time ago," he continued. "I think there are others, like Fitz, who -- when they see the reality of killing somebody, really have to ask the question that Coulson is probably going to ask himself: When you do that, aren't you the very same as those you're fighting against?"

"I don't think he's going to know for some time if this was a terrible mistake that changes him and maybe turns him into a super villain -- it becomes, really, a show about a team run by a super villain -- or not," he concluded.

Starring Clark Gregg, Chloe Bennet and Ming-Na Wen, "Marvel's Agents of S.H.I.E.L.D." will return to ABC at 9 pm EST on Tuesday, March 8.
