I once went to A&E when my mother was ill. Another patient on the ward was a young man who had been either punched or pushed over and hit his head on the pavement. His family were coming in and I spoke to (I presume) his father or grandfather who was very sweet and tried to calm me down - I was a young teenager and obviously very worried about my mum. The guy later died and I could hear his family sobbing / screaming down the hallway. I'd never really thought of that as murder but yes, I suppose it was
One punch murders are so sad on all counts. I don't think many in that situation expect that to be the outcome, they just want to play the big man for a minute.
Sucker punches are a bit different I think. To punch someone from behind or the side when they don't even know it's coming is dreadful. Again though, I don't think these people go out with an intent to kill. Often the degree of harm is unintended.
With a lot of violent deaths these days, all I see is situations that could have been avoided. If only things had been better, they'd have had access to better help etc.
Maybe fisticuffs was a better way than the knife crime we have these days. I just see wasted lives everywhere and I don't just mean the victims. It's really sad.
