Keeper of the Watch
As far as the Greed mechanic goes, you're not going to get penalized for looting a corpse.
It's more about decisions you make in conversations and quests. Do you extort people for money? When you've finished a quest, do you choose not to accept a reward, or press the NPC for more? Or threaten that you'll take everything they have? So in every context it's about a decision, not whether you leave gold coins in a dead guy's pockets.
Now, that certainly sounds much better.
