I mean... yeah? Just like it's on you for wanting Serini to get punched in the face for having a reasonable point of view that opposes the Order? I don't have any problems with my own position.
I do not get the "likeability" thing at all. What does that mean? Nice? Some of the worst things I've seen happen to stories (don't get me started on the later seasons of Parks and Recreation) were when they started buying into their characters being nice (even when they weren't) and thus deserved whatever they wanted, that they were more Special than everyone else in the story's universe.
In drama, different people have different moralities, and that leads them to different decisions, and those moralities and decisions conflict and escalate until they reach a conclusion. Right now, the Order's moral priority is "stop Xykon and enlist Redcloak to seal the Gates"; Serini's is "protect this Gate at all costs." They are coming into conflict. That's good drama to me.
Ah, but those intruders are the Special People of the story, and therefore deserving of what they want.
Are you trying to pretend Roy and V don't regularly insult their own teammates? Or that Roy isn't so arrogant he thinks he knows what's going on better than an actual Deva?
I find Serini's approach reasonable (the refusal to communicate with the Order has been covered to death already), and the "undeserved" attitude-- an Epic Rogue who built and has been for decades guarding what is now the last Gate upholding reality thinks she knows best how to maintain it is "undeserved"?-- really just seems like another way to say "uppity" to me.
