The way I see it is his options had run out, his heart had failed and he was going to die, they couldn't find a replacement heart, he had two options left: Take the pig's heart or die. I don't have a view myself, doctors are just doing their job and trying to stop people from dying. So far he seems to be recovering and as far as I know the surgery has been a success.
Eventually we will all die, if our thoughts die with us then there is no meaning to life and life is pointless. I always look for proof that human consciousness persists after death, to me that is the most important thing to know. If your thoughts and consciousness perish with your body then everything you do is for nothing. It is like painting a house that is on fire, the fire will consume the paint and make the painting pointless.
