I know you said you did, it was to provide context to others reading it and maybe not familiar.
As I said before we can all sleep soundly in our beds knowing you don't decide our laws...
The idea that a deliberate attempt to do someone harm should be considered the same as an act of carelessness resulting in the same punishment is absurd, which is what the 'manslaughter defence' is actually there to distinguish.
It also prevents juries having to find not guilty to murder if they feel there was fault, but not intent, but I guess being familiar with the law, you'd be OK with that...
