If one invariant fails, this means your program is not reliable anymore (also
when processing subsequent requests). Other invariants may become invalid too
and any assumptions made during writing of your program may not hold anymore.
This means that the program will most probably start behaving in an unexpected
way. I think in most cases it is preferred to crash the program than allow it to
produce invalid output and, for example, store it in a database.
