People are bound to be confused about "Rarest of Rare Crime" because law (All over world) defines 3 things, namely,
1) Homicidal Death Amounting to murder
2) Homicidal Death not amounting to murder
3) Homicidal Death amounting to "Rarest of Rare Crime". Unless you know the difference, you cannot judge the judges.
All impulsive murders are not necessarily rarest of rare crime. Rareness is not to be judged by number of knife blows.
