I do agree with you on the points that you have mentioned about the two classes of murder or shall we say killings. There is a third however and you have only hinted at it by mentioning other members posts, and that is the gang related murders. These gangs roam our Cities and towns in the UK looking for other gangs, and it is just to show face and protect their teritory, and when these gangs fight each other and a member gets killed, that is premeditated and should be rewarded with a harsh and long imprisonment. One other point i would like to make, and that is a person should never kill as the last resort unless it is accidental in self defence, or could not be avoided in self defence. This is not an argement against what you say, but just my personal feelings.
