Also question for you Nutella. If a person is brain dead but as a heart beat from machines, is it morally okay to pull the plug and kill them? Or should we classify that as murder as well as abortion since you are killing a human with a heart beat?
If the person is completely brain dead and has absolutely no chance of survival, then yes, it should be okay to pull the plug. The human no longer has any hope, keeping them on life support won't help no matter how long they stay there. So, while pulling the plug would technically be ending their life and does, indeed, fall under the definition of murder, there's no future or hope for that human at stake, they're already lost, there's nothing you can do about it, and the best choice for everyone involved would probably be to kill them.
The baby, on the other hand, not only has a heartbeat but it also has a future ahead of them, a life separate from their mother's. To end it simply because the mother doesn't want to deal with them is definitely murder and should be punishable by law.
