Till Shade is gone, till water is gone, into the Shadow with teeth bared, screaming defiance with the last breath, to spit in Sightblinder's eye on the Last Day. By my honor and the Light, my life will be a dagger for Sightblinder's heart.
Until the Last Day, To Shayol Ghul itself.

Fantasy is an area where it is possible to talk about right and wrong, good and evil, with a straight face. In mainstream fiction and even in a good deal of mystery, these things are presented as simply two sides of the same coin. Never really more than a matter of where you happen to be standing.

A young wolfhound must meet his first wolf someday, but if the wolf sees him as a puppy, if he acts the puppy, the wolf will surely kill him. The wolfhound must be a wolfhound in the wolf's eyes even more than in his own, if he is to survive.

I doubt you can understand the magnitude of the stupidity in your statement

It's not evil, Rand. I know something evil when I smell it. This isn't evil, it's just incredibly stupid.

What is too absurd to be believed is believed because it is too absurd to be a lie.
