Found this on the 'net, dunno how accurate it is:
Hate Level Title Aggro?
Level 1 You still have a fairly good head start, but they will not let up until they have found you and filled your heart with poison and pain. No
Level 2 They are close.�It is only a matter of time before you have fallen within their reach. No
Level 3 Can you not feel the hands that reach up from the bottomless depths of hell? Can you not feel the gaze of a thousand eyes, glowing red with anger and hate? Yes, No with sneak.
Level 4 The grip of evil is tightening on the very essence of what makes you who you are. Be forewarned, as it will not be long before you are confronted with a battle for more than just your life. Yes, No with sneak.
