If someone dies, it is meant to be that way. In the end, everyone and everything dies.
I can see ways that some of the Archangels would use you in war, and it ain't right. That's one heck of a power you've got there.
So long as you're not raising armies of the dead, so long as you stay away from the recently deceased, I won't have a problem with you. And you'll be safe here from any Archangel that tries to use you for your power. Where I come from, the Angels that serve Archangels do so because they are connected through the greater symphony. Through the Word they serve. It's a deep and powerful bond.
