His aunt is wrong, at 25 he is NOT a kid; and as for not meaning to hurt anyone he had to perform 3 separate actions deliberately - remove the paddles and place them on the victim, charge the paddles, deliver the shock (and all those after being told not to play with the defib). You might be able to do one of those accidentally, but in my book doing all three makes it murder. I've only been on the road for 6 months and defibs scare the s**t out of me because, as one of my instuctors said, they are one of the 2 pieces of kit with which we can kill someone instantly. I did hear about a consultant on a PHTLS course: the story goes that he wondered what it felt like to be shocked, so he set the charge to 2 joules and placed the paddles on either side of his head. He died, of course; but at least he didn't take anyone else with him.
