for 250 years Cadsuane has merely been doing what was at the time absolutely necessary! All of those men would have gone insane and potentially killed hundreds if not more others!

I fail to see why her relatively humane treatment of male channelers should equate to "poetic justice" should a man kill her. Elaida or some of the others who participated in the Vileness sure, but not Cadsuane.

"I am Green Ajah, not Red, but I have worn the shawl longer than any other sister living, and I have faced more men who could channel than any four Reds, maybe than any ten. Not that I hunted them, you understand, but I seem to have a nose." Calmly, a woman saying she had been to market once or twice in her life. "Some fought to the bitter end, kicking and screaming even after they were shielded and bound. Some wept and begged, offering gold, anything, their very souls, not to be taken to Tar Valon. Still others wept from relief, meek as lambs, thankful finally to be done with it. Light’s truth, they all weep, at the end. There is nothing left for them but tears at the end."

Clearly she gets no pleasure out of this activity... just sees it as a necessary function or even duty.
