Doesn't the game encourage the player to choose the more -- oh, what word to use -- "helpful" actions as opposed to ones that are more pragmatic, perhaps? For instance if you leave Redcliffe to its fate, you don't get the XP you'd get from fighting. You also lose out on XP (and some gold) if you choose not to do any of the Chantry Board quests. Of course, I suppose one could look at those things from a purely mercenary point of view because you do get paid.
I just have a hard time making some of the tougher choices because I tend to put too much of me into my characters. I do try to stop and think, "Okay, what would this girl do in these circumstances?" but I can't say that I can always stick with what the PC might actually want to do. Some things I can manage because I don't really see them as necessarily bad. My DNF slit Zevran's throat and married Alistair to Anora without blinking an eyelid. Her player felt a little bad about the latter, but she didn't mind it a bit.
On the other hand, my first PC was ready to leave Leliana in Lothering because she figured Leliana'd been eating too many deep mushrooms, but Alistair talked her out of it. She also went into the forest to kill Witherfang, but the Lady talked her out of it. She was going to annul the Circle, but Wynne talked her out of it. She was going to slit Zevran's throat, but he talked her out of it. Utoh, I'm seeing a pattern, here.
I do have a character that I want to take a more pragmatic, "eyes on the prize" approach. She was ready to leave Redcliffe to its fate, but -- yeah, someone talked her out of it. *sigh*
