That is explained. It's the Arl who supports you and he's a man who knows the Blight is more important than anything else and even says so. Killing Connor has Alistair shout at you in the camp - what else did you expect? For the Arl (Alistair's Uncle) to attack you? There's also the choice of destroying the Urn of Sacred Ashes which allows you gain powers that you wouldn't gain otherwise. Yes, there's a set path but there are many choices and ways you can chose to go along that path. DA was never meant to be a free roaming sand box game where you never have to finish the main storyline now was it?
And when compared to Divinity II or Oblivion - the choices and their consequences are much better.
