Wednesday Words and Thinking Thursday: DST?

I don't often do posts for Thinking Thursday, so I decided to do a combined one for yesterday's Wednesday Words!..

Deep sleep therapy (DST), also called prolonged sleep treatment or continuous narcosis, is a psychiatric treatment in which drugs are used to keep patients unconscious for a period of days or weeks.  - Wikipedia

But, for Thinking Thursday here's your question:

If a patient who consented to DST died, who would be to blaim?
