Killing the Emperor, Which CW side would benefit? Options

[ghastley]

The Emperor makes an appearance in a Skyrim quest, and it may or may not have anything to do with a DB contract. There was a discussion started on the Beth forums in this topic.

But which side in the Civil War do you think would benefit if he were killed? Stormcloaks, because it would weaken the Empire? Empire, because it removes the constraints from Tullius, and he might get the extra troops he's been wanting?
