We always try to preserve life no matter what. But is that the best way? What about a homeless drug addict that's been hooked for 20 years and destroyed his mind to the point where he can never recover. Should we still be treating his hep c? Or whatever illness he gets from his lifestyle? Or should the hospital be able to say "you did this to yourself" and kick him out? It seems like there are many instances where there is no chance of recovery, yet we still do everything we can to keep them alive. Of course we don't want to kill them, but should we let nature take its course and not save them? Is it nature's way of ending lives once they cannot take care of themselves? I mean if they were good people, then obviously they have someone that loves them and will take care of them. But if you were so shitty that nobody is willing to take care of you, then why do you still get to be saved?
