Would you rather die, or be unwound? Now he finally knows the answer. Maybe this is what he wanted. Maybe it's why he stood there and taunted Roland. Because he'd rather be killed with a furious hand than dismembered with cool indifference.
What's the point of living if you're going to hate the world? Guard your heart if you have to, but don't shut it away.
The moment you're loved, that's when you got your soul.
