Worst death in the show

If you were in the shoes of any character in the show who died, who had the worst on screen death of any character in GOT and why. Taking all matter or circumstance into account of course as far as how they went and their time leading up to the death.

My wife and I were debating as to who it was and I’m curious to hear the community’s thoughts as well. I said rob Stark, she said Ned.

What do you think?
