I confess. I stole the Eiffel Tower. I'm a thief and a crook. Take me away and lock me up. Confessing to something is evidence of guilt if a crime has occurred. It's not evidence that a crime has occurred. Being present for every death is only evidence of guilt if those deaths were murders. It's not evidence that those deaths were murders. Otherwise you could correlate the staff rosters with death certificates at every hospital or nursing home and find a large number of "serial killers". Especially if you get to cherry pick which deaths are suspicious.
