I guess one of Morlan's beliefs is that one should never leave a potential enemy the opportunity to get back at you if you have the chance to prevent it.

He's tidy like that.

So, "You can trust an enemy, so long as they are dead" yes?

Pretty much, yes. Although considering the nature of the planes, even that belief might prove to be false.

I think it was a great scene. Lots of dramatic tension. Bravo!

I'll admit that does sound uncanny. However, all the business of maintaining Morlan's balance is OOC stuff. IC he has no such tally, nor even a concept of one. He just does what he does, but it is what he is that makes him do things that kind of balance.

Conceptually, Morlan is an ordinary guy, like you or me, but taken to a fantasy extreme. He looks out for his family and friends, defending them with ruthless zeal. Otherwise he's out for whatever he can get, to better his own lot in life. Pretty much everything else is either irrelevant, or a resource to be exploited, or a danger to be crushed.
