You are all Alistair haters. I however, like to think of Alistairs betrayal as more of refusing to fight with the man that killed his entire family, and yet you let him live. How would you feel if the man that killed your family was allowed to live? Not very good, I presume. He isn't a dog, that should all hail the PC! (I get the feeling many people here think of Alistair as a whiny baby over the fact of Loghian. But he is acting like a normal human being in this situation), in my oponion, he ran away over becuase he's young and stupid. The Darkspawn chronicles don't count because it's a AU.
I mean, you guys really didn't take the time to actually talk to Alistair, when he was mourning over Duncan. He was about to cry over Duncan when you mention him, so if you keep Loghian alive, your pretty much keeping the man that killed his parental figure alive. And yet you guys also assume he's whiny becuase he doesn't stay with the PC when you keep Loghian alive. Well, to be honest I usually kill Loghian becuase 1. He puts elves in slavery to a crazed blood Mage. No excuses. 2. He would leave us all to die to Darkspawn because of how parniod he is about Orlaisans. 3. He sends assassins to kill the PC. Yeah.. What Alistair does is just nothing compared to what Loghian does. They're just as guilty (they're both willing to let Ferelden burn to get what they want.) and yet Alistair gets called whiny becuase some people skip past his dialogue...
Believe me I've heard all his dialogues and complaints, it's ok that he hates Loghain, but if he lives, then he doesn't only betray HoF and the Grey Wardens, he also betrays his country and his family he abandons everyone to die just because his tantrum, he maybe didn't know how but he knew that only Grey Wardens can take down an Archdemon, yet he runs away, all he cares about is his vengeance, you can be either an angel or the biggest jerk on the world, that doesn't matter as long he can get his vengeance, however if you refuse, he'll just dump everything you may have done for him, so at the end of the day, he is not better than Loghain, furthermore he also murdered Yavana and turned against the Inquisitor (both count as betrayals and Darkspawn Chronicles is not on display to show us what a good person he is), all he does is get aid from people and turn on them when they are not longer useful to him. Yes, I do hate Alistair but you better understand that such hate is not fortuitous.
Besides, the discussion was that he is worse traitor than Morrigan, which is quite true, if you want Loghain to pay for what he has done, you either execute him or even better: you have some poetic justice on him and then abandon him to die on the Fade.
