I’ll have to rewatch that scene but I’ve watched the episode twice. It wasn’t my impression that he accidentally stabbed himself but that M’Benga was pushed to defend himself and stabbed him, thus finishing his mission on J’Gal.
I know some people feel that M’Benga killing Dak’Rah felt disingenuous to Trek but I actually liked seeing that even though these characters are diplomatic and controlled have their limits of humanity and right and wrong and that some atrocities truly are unforgivable. The characters aren’t perfect and make mistakes and I like that - I feel like it’s a more accurate representation of humanities struggle for peace.
I’ve had the same thought. Can anyone make an instance and it’s automatically federated? It would make sense that to join the federation there would be an application process, gaining approval by receiving so many votes by already federated instances. But that doesn’t exist as far as I know and I’m sure would create a whole other set of issues and politics and skew the general idea here that this place is decentralized
