Morphine suppresses breathing so that you suffocate. Given that the kid is already pretty non-responsive to stimulus (bring diffy ~70% of his CNS) the tranquilising effect of opiates would be a complete waste.
Peckerwood hahaha! You fücking tool. You were the one who suggested giving the kid morphine you fücking bellend. I'd say that that's putting him down like a fücking house pet.
You've been knocking back too much of the moonshine. Fück off to bed, and sleep it off.
Not strictly true. You can be 'helped' on your way via painkillers if terminal, most hospices will discuss that with the patient and next of kin. They ensure you are not in pain up to the point that it's the painkillers that push you over the edge, not the terminal illness itself.
