Well, I'm not a huge fan of the notion at face value
I see your point on needless death--but, to be fair, this next episode will be these characters in a war zone, where random death does tend to happen.
I've been leaning pretty heavily toward Kara's resurrection being because she's a hybrid, but the flashbacks, to me, seem to point really strongly in the direction of "everyone comes back to life".
