I don't think being involved with Penny's death really puts Emerald beyond redemption, at least until it's firmly established that Penny was sentient, and not just an android simulating human emotions. I suspect we'll find out the answer to that question this upcoming volume.

And don't say, 'she had an aura, so that means she had a soul'. There's no reason to think that they couldn't create an artificial aura without giving her a soul. We don't definitively know whether or not she had one, and can't know until the show tells us.
