Rosen's response to Blackwall's accusation of corruption in the Inquisition
In the throne room
"You believe trading political favors is corruption?" Rosen asked Blackwall calmly.
"Yes! That is a part of the exact definition of corruption, Inquisitor."
"You are right."
"I- What?" he stammered, clearly confused by Rosen's quick agreement.
"Yes, what I requested be done was corrupt. Using what we did for the empress in order to request a favor was wrong. But it was also the right thing to do."
"How can both possibly be true?!"
"It simply is." Rosen crossed his long legs and steepled his elegant fingers where he sat on the Inquisitor's throne. "You are not looking at the bigger picture, Rainer. The Inquisition as an organization is temporary. When, precisely, it shall be disbanded, I have yet to decide. But it will be at some point in the future. I have already vowed so before the Maker and Andraste, as well as Mother Giselle. Life, however, is potentially infinite. And infinitely more precious than any organization created by people. I made the choice to sacrifice some of the Inquisition's good reputation in order to save you. I could not allow your life to be taken when I had a way to prevent it from happening. We may not be close friends as I consider Morrigan, Cassandra, and Varric, but you are still my friend."
"Tell me, Tom," Rosen continued. He leaned forward in his seat to study the other man closely with his intense blue eyes. The red circles flared briefly like fire as he spoke. "Which action do you think would ripple out and affect the waters of the world most strongly in a negative way? Using the Inquisition's political influence to save you from death? Or doing nothing? Allowing my friend to die, to be killed, when I could have prevented it? Killed for a mistake he made years ago and has spent his entire life since repenting of, as well as doing good deeds?"
