Haha, Hawke being the Inquisitor meant that Corypheus would have won. He saved no one, he saved nothing. He could barely keep his city standing.
The thing that's really funny about this is that people are quick to dismiss the fact that of the three protagonists we've gotten so far, Hawke is the only one that was forced to operate without formal support from anyone anywhere. Just look at what she had to deal with:
An ineffectual, spineless Viscount.
Qunari zealots that tear through the streets over a lousy book.
A lying companion that kept the very thing that could have solved that problem earlier on.
A corrupt city guard and a useless guard-captain that couldn't help you when it really counted
Useless Templars that can't keep anyone in check.
A mad Knight-Commander who cannot be reasoned with.
A shady First Enchanter who is of no use to anyone.
Bloodmages. Bloodmages everywhere.
A Grand Cleric that was infuriatingly neutral and just spouted useless platitudes to the bitter end.
And a terrorist freedom-fighting potentially former companion that decided to just blow **** up, even if you gave him the boot years prior.
Not even the Warden had to deal with this. Much of the character's power came from the fact that factions were lining up to rally to the cause against the Blight, of course after you did their errands. It was super convenient that just about no one of importance was taking Loghain's declaration of the Wardens as outlaws seriously, not even that minor character Templar in Lothering.
The best part though is that Hawke can beat Corypheus in direct combat, but just couldn't counter his ability to jump from one blighted creature to another. Even if she decided to kill Larius or Janeka, he would have just transferred over to anything carrying the Blight within reach.
