Do medics seriously think that a previously suicidal person will change their mind about life, and will come to appreciate life after becoming brain damaged, disfigured and/or quadriplegic?
And isn't saving the life of people who don't want to be saved "playing God?" It's not like they'd have to do anything to actively kill you-they could just wait for nature to take its course.
Are medics just greedy?
As someone that goes to med school, i think i'm somewhat qualified to answer this.
I think it's mostly a matter of, that's just what we do, we save lives, we aren't there to judge if we should or shouldn't save a person.
Like
@autumnal said, we don't even have time to think about stuff like that in many situations, we just act on what we know how to do.
Not to mention, a lot of times, if the person is guaranteed to be a vegetable for the rest of their lives, there is euthanasia in a few countries, you can turn the machines off, etc.
So it makes sense to try to save someone and only later, if everything goes wrong, pull the plug.
However, i can see how it can be really scary and frustrating in cases where these options aren't there.
Another big problem is, again speaking from the perspective of a med student, if we can save a life, but don't, there could be lawsuits up the ass if anyone finds out.
I had an entire subject for one whole year of "Ethics", but it was really "How not to get sued, or win if you do".
I don't know the situation in other countries, but in Brazil suing doctors for literally anything is common practice, since it is one of the best careers salary wise.
So people think "that son of a bitch has money, let's get some", so even in cases where the person wants you to let their family member die, for example, it's possible you'd still get sued if they somehow found out you didn't do everything you could to save them, just so they can make those extra bucks.
So yeah, that's another reason medics do it, so they don't have to deal with things like this, as in saying "I did what was demanded of me, now leave me alone".
It's awful, but it's the way things are unfortunately.
