All the enemies are dead except the boss who says he surrenders, what do you do?

[Vizzerdrix]

If you have that option available, then take it. Life is too valuable not to make the attempt if success is guaranteed like that. Though, you start to get into the problem of free will and autonomy. That is a much more murkier issue than I care to argue about.

I propose unlife is equally valuable, or even more valuable. The undead make better laborers, and have more time to see, understand, and learn from the error of their ways. They are also cheaper to feed and house. For the most part.
