This story does that, AND it makes Kara just as obnoxiously judgmental toward Thara as Lois is being toward Kara over the death of Lucy (Superwoman) Lane. Kara and Kal are both there when Zor is killed, and have tons more experience (well, Kal does anyway) having superpowers than Thara did at that point, and Thara is also Kara's age, and has no business being 'head of security', and Kara's being unreasonable about accusing Thara of being negligent. This is published after Lois has the same reaction toward Kara who 'killed' Lucy accidentally and only in self defense. I think DC wanted to say "See? Kara's just as bad."
