Well, he wouldn't have to protect his family unless there was a danger that he knew could be brought to them. I agree at that point that, it does indeed sound suspicious, but at the same time, what would he be protecting them from?

Why not from the truth? Nex was talking to Seravee about wanting to kill someone, someone suspected to be a killer. Would Jster not be protecting his family from the truth by picking off those who would want to reveal it? Like Shy, who argued with Seravee about missing the dead body of Drakel. Like Nex, who was so bloodthirsty to lynch (shoot) Alpha that he likely wouldn't blink if Jster was revealed as the killer. 

To the wolf, the truth is the number one enemy.
