Hah, depends entirely on how attached I get to my next DA hero. I mean, if I had to choose between my Warden and Hawke, bye Hawke. If I don't care too much for my next hero and it's between Cullen living happily ever after with my Inquisitor, then yeah, by Future Next Hero.
Heh, it's the other way around for me. My Warden is a Warden first of all, and a Warden's life is sacrifice. She would absolutely sacrifice herself without a thought to save Hawke and Trevelyan, who (despite being figures of authority) she would consider innocent civilians in the war against the Blight. She is dead in my canon playthrough, so it's not like it would be the first time she gives her life away to protect the world. My Hawke... I have so many feelings about Hawke. She never wanted any of the sh!t she was pulled into, she just wanted to get by and ended up losing so much... I could never give her such a meaningless death when she's finally getting some semblance of normalcy and happiness in her life.
The Abyss choice for me is always to sacrifice whoever the Warden is for that playthrough, in any case, be it Stroud or Alistair or Loghain, because to me that's the basic premise of the Wardens, that's what Wardens do. In death, sacrifice. If the choice had been between my Warden and my Hawke... bye again, Warden.
I am pretty emotionally invested in my Inquisitor, though, so a Sophie's Choice for a next game would make my nose twitch endlessly. Not even for herself, but for Cullen's sake. I always thought there was something beautiful and strong in Alistair carrying the weight of his dead love in his heart for the rest of his life (lol, poor sod
), but... I couldn't do that to Cullen. He's been through so much, he's seen too much sh!t, and I basically just want him to be happy, period. No more drama, no more angst, no more heartbreak... just puppies and happiness. So if I had to sacrifice my Inquisitor in a next game...? Tough question. I would if Cullen had been lost already - but while he lives and loves and has his happy ending, I don't know if I could bring myself to take that away from him.
