More me the biggest *** thats the darkside option came when going after the prime with the mandos. You get a call from Lana, who very correctly points out that if the Mandos make it out of this unscaythed they would tear through the galaxy once more. And then, when given the choice, its a light side choice to help the spartan, war loving, mandos, and a dark side to leave them in the dark. I mean, both are really dark side. Why then, is the lesser of the two evils, to help the mandos survive so once this war is over, they can then turn on the pubs or the imps again with no problem?
