Let me give you an example and let me know your take on it. Let's say there's just me and a little kid at a pool (and I don't know this kid)(no lifeguards: nothing other than us two). I am dangling my feet in the water and the kid starts drowning in the deep end. I am the only one around that could save this little kid, but I don't want to risk getting an ear infection and since this matter (i.e., the potential ear infection) pertains to my body I think that I have the right to not consent to saving this kid.
Do you think I have the right, in that scenario, to not consent to saving the kid? I don't think I do, because consent doesn't matter in the instance that one could save someone else's life without any foreseeably significant unwanted bodily modifications.
Here's another example I would like your take on. Imagine I go out and stab an innocent person in both of their kidneys. The cops show up, arrest me, and the victim gets sent to the ER. Turns out, I am the only one with the right kidneys to save them (viz., there are no donors available that would match, etc.): do I have the right, as the egregious perpetrator, to keep my kidneys if I do not consent to giving them to the victim?
I don't think so: what do you think
Cute. Even if your name wasn't Bob, I'd know you were a guy. Ear infection, eh?
If you want an analogy, let's give an analogy. Let's say if you jump in the pool you'll get mystery disease X. Folks who get mystery disease X have a 1.4% chance of "serious morbidity", a 32 per 100,000 chance of dying and about a 33% chance of needing major surgery.
Next: "Generally speaking, there is legally no duty to rescue another person.
The courts have gone into very gory details in order to explain this. In Buch v. Amory Manufacturing Co., the defendant had no obligation to save a child from crushing his hand in a manufacturing machine. The court suggested an analogy in which a baby was on the train tracks – did a person standing idly by have the obligation to save him? Legally, no. He was a “ruthless savage and a moral monster,” but legally he did not have to save that baby"
However, mystery disease X stats are on average. There are some folks who get it who have a 25% chance of dying. Any thoughts about judging those who don't jump into the pool?
Another thing: I can tell you that the kidney stabber convict situation is well established in the Medical Ethics field and it is quite clear the stabber cannot be coerced into donation of a kidney.
Lastly your commentary is missing another angle in the abortion situation and that is society and the courts give very broad powers to parents to manage the healthcare of their minor children. Thus it stands to reason that it should grant even broader powers to those governing potential children (who are not minor children).
