Consider Phlebas (Culture, #1)

by Iain M. Banks

“I really don’t understand you, Horza. You must know how many species, how many civilizations, how many systems, how many individuals have been either destroyed or… throttled by the Idirans and their crazy goddamned religion. What the hell has the Culture ever done compared to that?” One hand was on her knee, the other was displayed in front of Horza, clawed into a strangling grip. He watched her and smiled. “On a straight head count the Idirans no doubt do come out in front, Perosteck, and I’ve told them I never did care for some of their methods, or their zeal. I’m all for people being allowed to live their own lives. But now they’re up against you lot, and that’s what makes the difference to me. Because I’m against you, rather than for them, I’m prepared—” Horza broke off for a moment, laughing lightly, self-consciously. “… Well, it sounds a bit melodramatic, but sure—I’m prepared to die for them.” He shrugged. “Simple as that.”
