Upfront, originally this episode didn't connect with me because I didn't feel like I knew the Narn, Minbari, Centauri, or Downbelow well enough that their outrage at Deathwalker and what she did resonated with me. It was like, "I feel bad for them, but I'm not invested enough, so I'm looking at this from the outside." Now I feel like I know them better so, strange as it sounds, they're anger resonates more with me even though I've never seen what Deathwalker has done. That's critical, so now I'm invested in their anger about injustice.
The next thing I appreciate now is the tough bind that it puts Sinclair in. He has to navigate how to deal with Deathwalker according to law while balancing and dealing with the outrage from the people of the station. He has to walk a very tight rope.
The Ambassadors also have to make a tough choice on voting what's in their jurisdiction and what's not, which shows the gaps and blind spots in interstellar law.
Finally, there's Deathwalker herself. Maybe she wants to right the wrongs she did. It's possible some of that is in there. But I think it's also true that she wants people who hate her to hate that they benefitted off of her. It's out of spite. And immortality is a whole other moral/ethical dilemma. Whether or not it's a curse or a benefit. That can and will be debated forever. But Kosh makes the decision for them, and makes sure Deathwalker is killed, stating that Humanity isn't ready for immortality. To be honest, I think the Earth Alliance would've come to that same conclusion, but the Vorlons didn't give them that chance.
Overall, re-evaluating this episode, I give it an 8.
