I don't know if you knew that Michael Schiavo was a nurse who went to respiratory shcool and nursing school. This explains a lot of things.
1. Male nurses are often weird (not you fastac). Not always, but this is my experience.
2. As a health professional, he would commandingly go to her room with the chart,close the door, bully the nurses, say don't listen to the doctors listen to me(the only time this male nurse had it over a doctor because she was his property) and finally repeatedly give insulin with needle marks in hidden areas because come on: whenever you hear of sick bastards giving insulin to kill someone in the news, they're always nurses!
