TS2 Book 3 Chapter 180

“People will always be the same no matter how they wish or try to change. They can do whatever they want, but they can only change the way their true nature manifests, not their nature itself. A liar will always be a liar, he may just change his lies. A fool will always be a fool, he may just hide it better. A coward will always be a coward, he may just avoid danger better.”
