How do you compare that to what happened to Steve Erwin?
OK I'll explain it. Irwin was filming a docunentary on deadly predatory ocean mammals. He was swimming close to a stingray without any precautions. I would think he felt confident enough based on his past experience that he didn't need to.
Tay probbaly felt he could fix the generator with power on based on his past experience with electricity.
That is, they were both over-confident, and it cost them their lives.
