You know what struck me about that? The guy's 23 and he's killing his sister so she doesn't have to go through another procedure for him. Um...he's 23...all he has to do is refuse the procedure and she gets her life back! I pretty much stopped watching after that, I had come to respect the show because of their excellent writing, and once you get to "perversion of the week" and plots with a hole as big as "the 23 year old doesn't know he can direct his own medical treatment" I had seen enough.
Oh it was ridiculous, trying very hard to show Catholics as hypocrits, as if one would justify murder by avoiding suicide. It was beyond absurd.
