Although he plays the role of a killer, Moses denies that his character is the bad guy (antagonist), "He is a cold-blooded killer, not considered a big bad guy, the drama is a bit science fiction, there's a lot of emotions (joy, anger, sorrow), he just wants to protect himself, doesn't want others to know his past that's why he does all these bad things."
