OK, broken program state can result in an exception thrown, but the opossit is not true. The user is unable to make a difference when the exception has been thrown because a broken program state or because of the logic.

In addition, if the program is in a broken state, it is even more possible that the program crashes than it throw an exception.

My preceding question should be: Why do you associate a broken program state with an  exception?

So if the user program can throw exceptions and most of them can,  the user need to catch the exception in order to unwind the local variables.
