Because she is a kidnapped victim of the cult, not its enforcer. She even mentions herself after being freed that she had no control whatsoever of her actions and relates to Dark Urge the most about this.

But you only know this after you spare her. Before that she is a fanatic leader of the absolute. There is nothing that tells you she will turn against them if you spare her.
She's not different from Viconia. Viconia also investigated and wanted to destroy the cult. But in her case there is no doubt. She really is the enemy of your enemy. So should you give her the prism then ?
