Always slay him where he stands.

You know that part at the beginning where you get to choose a name for the avatar and answer questions about his character? One of the questions is this one:

You fight a warrior you hate, and knock his spear from his hands.
Another blow and he will be dead.
Will you (a) let him surrender, and spare him if he does, or (b) slay him where he stands?

In this question, always choose (b) slay him where he stands.
This shows you're not a wuss.
