"Hm, I wonder who made me do that stuff?" Cyrus said, "Or at least use it to hurt others. I learned that certain medicines used together can cause horrible pain for the purpose of avoiding bad drug interactions. Yes, I tested it on people when we had prisoners, and sometimes, just gutsy volunteers, but I really don't think that compares, especially when it's others who chose to use that knowledge to harm many others. Besides, you shouldn't even talk to me about rectifying my sins. What do you think I've been trying to do in my time away from here? If I wanted to kill and be cruel, I'd have done it."
