Of course they should be treated.
Are we now going to become selective about who receives the necessary care? I believe that the NHS is there to give emergency care to those who pay their taxes for it. This man obviously got drunk and did something stupid - for which his life must pay the forfeit? I mean, if someone is paralyzed from the neck down, they're not going to last very long without care.
If someone exceeds the speed limit, they should be left moaning in the middle of the road if they crash? Is time going to be wasted by paramedics deciding whether the case is worthy of treatment?
No. Because unlike you, these people have to live in the real world.
Can I ask you all a[nother] question?
A lot of people would not be able to scrape the money together for private care, and be left to die slowly at home, with no NHS to ease their pain or perhaps give them the chance to overcome their affliction.
If your mother/father/sister/brother/spouse/close friend were diagnosed with lung cancer, after a lifetime of smoking, would you applaud a decision to deny them treatment?
The honest answer, again, is no.
