I would put it like this:
You go for dinner and order fish.
The fish arrives but is stale/overcooked/etc....
It is stale bcoz the Fridge is bust , overcooked bcoz the oven is bust etc.
But the one to be rebuked first is the waiter who has just got it to the table.
The LAST one in the chain of events.
It is also like the 10 members of a football team being unable to prevent the ball from entering the D now expect the goalie to stop it.
It is a team effort and the whole team is at fault when anything goes wrong because any 1 person could have stopped the chain of events leading to he event.
Historically, where the Pilots have died, the C of I have held that the Pilot is at fault for causing the accident but cannot be held blameworthy (since he has met his maker in the accident), since he cant defend himself.
