And it's so easy when you're evil ...?

The thing about playing out your Dragon Age character the evil way is: it's not really fun, at least not for me. I thought it would be great to piss Alistair off, bully everyone around and generally be an asshole, but. It's just ... not.
For one thing, I am too much of a goody two-shoes, so pissed off characters make me nearly physically uncomfortable (yeah I know it's just a game, but - aaaah, I cannot bear it). Another thing is that I am a crazy perfectionist when it comes to computer games and character disapproval annoys the hell out of me because IT'S RUINING MY PERFECT GAMEPLAY with perfect results and each and every quest solved.
Besides, I feel like you're missing out on a lot of quests (ergo: experience points) and there's no real (evil) compensation for them. (Example: if you refuse to help out the people in Redcliffe, you'll miss out on an entire area with quests and battles.) MEH. Being evil isn't always that easy, it seems. Or is it just me?
