I feel sad at how all of them die, ultimately. I'm not looking forward to the Inquisitor's story being over, but I guess they'll offer us a chance for her to sacrifice herself, too.
I think that's probably the best they can do. I mean, have you seen Hawke in the Fade? Her appearance was amazing, the quest was fabulous, but when MY Hawke started saying "WardensBadBadWardens", all I could do was just sit open-mouthed and blink. My Hawke never judged, and my Hawke respected the Wardens - her lover is one, her brother is one. Those words? That wasn't Hawke, that was the writers turning Hawke into their mouthpiece(since Loghain was pro-Wardens, someone had to represent the opposite point of view).
So, rather than seeing my Inquisitor turn into a stranger and start saying some stupid things(like she holds a grudge about Solas, or how she looks forward to continuing with the Inquisition, instead of finally shutting that monster and running away), I'd rather see her sacrificed.
