On Sunday night's episode of The Walking Dead  viewers learned that the Terminans were the cannibalistic group called The Hunters from the comic book series.

One of the reasons that the Terminans still exist is because Glenn (Steven Yeun) wouldn't let Rick (Andrew Lincoln) kill them.

"I think that's what's cool is Glenn holds out hope for humanity and for redemption and for salvation for people, but this world keeps screwing it up," Yeun told Entertainment Weekly about his character. "I wouldn't be surprised if you see that affect him a little bit as it goes on. That's what's amazing about this world is that even the Terminus people - you could justify what they're doing in that world."

Yeun continued to say that you could justify the Terminans actions because if the world is "just 'how do you survive?' then they're not necessarily pure evil, they're just doing what is necessary to live.

"It's such a sliding scale of what's right and what's wrong and it depends on what viewpoint you're coming from," the actor said, "but clearly even within the group you see people sitting on different sides of that meter and that gamut of choices."

Gareth (Andrew West) was famously shown eating Bob's (Lawrence Gilliard Jr.) leg on Sunday night's episode once it revealed the Terminans were cannibalistic.

The Walking Dead airs Sunday nights at 9 pm E.T. on AMC.
