Is there something I'm missing?
It just shows the team of writers doesn't really care about Halsin, this is what I see here (remember their interview? They didn't really talked about Halsin, felt like they avoid this topic).
Also, I remember that Halsin is not that friendly towards Shadowheart in Act 2. Yes, he travels with Tav and the gang but he is not fond of Shar, of course. He even had a dialogue with SH, in which he trolled her, said about her "bleating", but I have a feeling it is a piece of his EA personality.
So yes, this is one more reason why this ultimatum scene is bad and illogical.
