My character thought he would help against The Mother. Big mistake.
Said character also thought he made a compelling argument about darkspawn being just as capable of sentient thought and varying morality as any other race, and that it's not right to discriminate against them for something they can't help (mindlessly following the Taint) or didn't do. Then again, said character was a city elf, lived with the hypocrisy of humans with power all her life, and just couldn't bring herself to do to the darkspawn what she wants humans to stop doing to elves. (Paint them all with the same brush, prevent them from going off to build their own society and live their own lives elsewhere, condemn them to death or wandering like animals, etc.)
In real life, I'm extremely neutral. If they can find a way to continue their existence without trying to blight out all life, kidnap, violate, and transform women into horrific breeders, or even bring harm to other races, they can have at it. Otherwise? Yeah, I vote to stop them.
