Thanks for the chapter!
Instead of talking she should make sure the hero stays down. If he's definitely and permanently dead she's wasting time, and if he isn't then should take him out before uses some OP skill or some Hero ability or item and recovers.
If really want to be practical would strip everything off him so wouldn't have any buffs from the special Hero gear or recover/escape using a special one use item like an elixir or equivalent of WoWarcraft's Hearthstone. Remove his hands and eyes so can't cast or aim spells (tongue too if want to be thorough even if merciless,) one leg so can't escape, and multiple cursed items that weaken him prevent usage of magic, won't interfere with each other, and really hard to take off. That way he can't fight or cause trouble and since alive the hero attribute or whatever he possesses that makes him a hero won't be passed to someone else due to dying preventing another hero from being chosen and rising up. After all, divine blessed heroes chosen by a higher power appear one at a time to provide a means to defeat the demon lord while minimizing the number of OP people running around afterwards.
