You won't pass an emissions test, periodically required in most states for re-licensing the vehicle, with a bad converter. Your car also won't run very well with a bad converter (less efficient, lower gas mileage).
However, that's not really the worst case scenario. It's actually possible that it could catch on fire.
The definition of a worst case scenario is pretty much self explanatory. A worst case scenario is the worst thing that could happen in a given situation.
Could be a clogged catalytic convertor Could be a problem with vacuum lines or (worst case scenario) your transmission.

This was the worst scenario he'd ever been in.
You have no oil pressure and are doing permanent damage to the engine internals which will result in overheating and the engine will stop running, maybe seize maybe break, might even catch fire. If the check engine light flashes while your driving and you continue to drive it, you will probably cause serious damage to the catalytic converter which will cost $$$ to replace.
