I'm pretty sure I mentioned before in a comment - but using Xander as the Best Case & Reason for taking the moral high ground works great.  Another alternative would be to simply asked the warrior spirit if he would help them fight against the First Evil and then return him to his people to fulfill his role as His Peoples' Guardian.  But, Xander's reason and choice, it's probably the best as humans and demons, spirits and other supernatural beings must depnd on themselves for this world saving power struggle. 

leave it to Xander to be the voice of reason.

good read, thank you. xander being logically and morally correct, priceless. giles does not bear up well in comparison.

i'm seeing xander through new eyes as well, now...that was pretty cool of him...great chapter, love :)

Wonderful chapter - i love xander's speech. He had the whole rationale down right and as the heart saw it as it should be seen. What if it was Buffy - what would they want done? Great chapter and excellant points

Xander was never finer.
