The definition of victim implies the same as "dead passenger". The families of dead passengers would be stretching the definition, at the very least it's not the most obvious definition in this case
>a person harmed, injured, or killed as a result of a crime, accident, or other event or action
"Victim's family" is how people would normally refer to them.
You’ve taken that in a different direction than I meant. I’d absolutely agree surviving family members are victims too (albeit I’d call them victims’ families for clarity), but none of this will stop say a well motivated prosecutor from arguing that these contracts were signed under duress, bad faith, or include some kind of “unfair term” (which would invalidate a contract in the UK at least)
Contracts with whom? A member country EU court with a dead passenger could presumably make life very very uncomfortable for senior Boeing management.
