Imagine a man who invented something else. A flying car, for example. It is beautiful, all new materials. He says, I am an engineer, a Princeton grad, trust me, I have been working on the prototype for that many years, i have consulted all engineers in my hi-tech state, bla-bla. We’ll be the first group flying in a car to mount Rainier. With your love of travel, you have been to the space, to the Pole, this will be unique, totally new experience, you pay me $100 each for the gas, that’s all.
So he gets 3-4 people in, gets behind the wheel, takes off, then his invention falls on the ground and everyone dies.
Is this exactly getting away with murder? I don’t think so. He was that overconfident driver who ruined himself, his creation and the passengers.
Or simply, people who trust someone saying “I know how to do it”, should, in fact, use better judgment? But consider this, at least one of them, maybe more, trusted other people saying “i know how to do it”, and got back safely? So they previously had positive experience with people saying similar things.
