If they were just going to defeat and kill Stannis in this episode anyway, wouldn't it have been better to have him die because he made the nobler decision to not sacrifice his daughter in the previous episode, and that decision cost him the war because he did not honor the Lord of Light? Have him find some bit of redemption in the fact that his love for his daughter outweighed his ambitions?
As it stands, when Ramsay's Rohirrim rode his armies down, I didn't care, because I had nothing invested in Stannis any more after last week. He was always an asshole, but killing Shireen pushed him way over-the-edge. So it was just one irredeemable piece of shit destroying another, and I felt nothing during the entire scene. Seems like a missed opportunity to me.
To each his own, I disagree with you 100%.
To me the Stannis bits were by the the highlight of the episode. Here is a man who sacrificed everything, including his beloved daughter, to try to save the realm from what is coming from the North. He had (almost) literally nothing left because he gave it all up, and only after he's been made to give up everything he held dear does he finally meet his end. That's tragedy.
Besides, would you want Shireen is Ramsey's hands?
No, I think that if Stannis was to loose, this was the way to go.
