Killing vs Letting Die, another hypothetical case

I just read something on the internet in which part of the discussion talks about James Rachels' idea on killing and letting die, and one of the example used seems to be less extreme as the inheritance one we learned in class but nevertheless the first case involves letting die and the second case involves killing. So is case (ii) morally worse than case (i)? Will this example make the two less different to you?

Cases 

§     (i) A unconscious patient will almost certainly die unless paced on a respirator. His family explain he has expressed a clear desire not to be placed on one. He is treated according to those wishes and dies.

§     (ii) Case i, but the man is placed on the respirator before his family arrive. After his wishes are explained, he is removed from the respirator and dies.
