Why would I want my enemies to run away as opposed to killing them? Won't they just return to fight me anyway. There's something I'm just not getting about this.

It gives you some breathing room if you are low on health or are being overwhelmed

This^^^ plus when you use turn undead, it takes a second or two for them to turn and run....free hits Even if their too strong for the spell it will stagger them for a second or so. Plus turn undead is a great spell to lvl restoration with

If your a pure mage with 700 mana, 100 stamina and 100 health, when you get cornered its good to hit guys with fear or turn undead, just to keep them out of your hair while you fight the other dudes. Its pretty much to keep a mob of guys from killing you.

Ok, thanks, all!
