Such a hypothetical would be reasonable in a criminal case against the person who set the trap, as it goes to the core of why setting such traps is illegal. On the other hand, the decedent wasn't a firefighter or other legal first responder. He was a crook.
I would have no trouble with criminal charges against the man who set the trap, were he still alive, but I see no reason the decedent's family should get one penny from his crime.
