 The level number is used extensively in the space opera game I am currently working on. In addition to dealing with things man was not meant to know, it also covers general acts of evil and depravity.

These impulse points may only be used for effects the GM determines that further the characters fall, and yes saving your hide so that you can further menace the galaxy counts. 

While these rules sound like they would only be good for tracking an opponents fall, they can be used to chart a hero's decent. The first few levels can easily represent a slippery moral slope. The GM is encouraged to keep track of them in secret.
