The demand for help was not something that Do'rhajul expect, particularly since he had no reason to believe there was anything left to help with. Without the background knowledge that Sabine possessed for context, her ramblings sounded almost nonsensical to him. The anger of such a powerful mage would have been something that most would fear, but Do'rhajul clearly no longer feared any such consequences, so he was not beyond arguing with her. 

"Towers? Swallowing Nirn? What are these absurdities you are speaking of? You do not need to search for anything; you have already stopped Vile's followers. Unless you intend to keep hunting them down, but you have already said that you do not desire revenge." Do'rhajul responded, letting out a huff and looking away. "I do not understand what you are talking about, but I am sure I cannot help you with anything. The most I can do for your people is to give them something to cheer about when they hang me in front of your clan. I have...killed too many. It was always painful to do, but I thought it was necessary. I thought it was for the greater good, that more lives would be spared because of those that were taken. But I am no 'General.' I am a pawn and a murderer. Whatever foul intentions Vile had by spreading lycanthropy, I allowed it to happen. I was responsible for the early successes that allowed Vile's cult to expand his influence. They were inexperienced and disorganized at first. I did not merely fight for them, I organized them. I built their command structure, their training principles, convinced them to focus on an intelligence network. Had I not prepared them, you would have defeated them within a year, perhaps two. It is not justice for me to go unpunished."
