Re: The cost of killing damage
Yes but do I know the dice value difference between a knife wielded by a guy who can throw a motorcycle at me and an ice cream truck being wielded like a club? In a superhero world, even with analyze skills, the GM particularly needs to be careful about how his NPC's make decisions.
That presumes that all participants view reducing uncertainty as the surest means to maximizing utility. Since we really should be talking about the players, yourself included, rather than the characters this presumption is, I hope, unlikely. In an RPG increasing enjoyment (Yours and Other Participants) should be the surest means to maximizing utility. One way to increase enjoyment is good roleplaying, one aspect of good roleplaying is understanding that characters (Player and non) are going to have different views on maximising utility. Reducing uncertainty is one, sure. Increasing reward, delaying or preventing punishment, delaying/denying another participant's reward, assisting other participants are all common methods of maximizing utility particularly since we are playing non-zero sum games.
