I'm not disputing that, but that's not assisted dying.
A basic example of the difference, you are the sole witness to a motorcycle accident, the rider is bleeding out in front of you, you have basic medical knowledge. You have 3 choices
1 - You can try and save him even though he's in great pain and you're unlikely to be successful but you may be able to ease his pain a little bit with the packet of paracetamol you have (palliative care)
2 - You can check him over and then do nothing (withdrawal of medical care)
3 - You can end his suffering by hitting him with a brick (assisted dying, or as the law stands, murder)
