This place is great at 'moral outrage' the finger pointing stuff. At the end of the day we have a very unforgiving hobby - as I tell my friends if iot all goes right it is pretty boring, if it goes wrong it very exciting, it is goes very wrong its nasty.
Callous though it may be this is evolution in action. As for the hirer or some other party being at fault? If you cann't take responsibility for your own well being and actions then you are not going to last long.
