Multiheaded said his/her (it's her, right? >_>) utility would increase, not happiness. If this is true, then, ignoring oppurtunity costs dead is what daenerys and other baby killing advocators ought be, subjectively-objectively for multiheaded.

edit: but it's almost definetely not true. Utility was probably being conflated with something, or Multiheaded was biased by emotional state (was REAL MAD, in less technical terms.)
