Whilst the T7 is ETOPs compliant and thus able to fly 3.5hrs on a single engine, if resulting damage had subsequently progressed a single engine shutdown (damaged fan blade, increasing engine vibration, etc) and there was deteriorating weather condition at all reasonable alternates, attempting to balance asymmetry with strong windshear (swiss cheese), may well have occasioned the matters where a collective wisdom could be applied when the CVR stops recording.
...And the presence of such factors would have been considered in the decision making process. The idea is to assess ALL relevent data ON THE DAY- not what might happen in some fantasy situation.
If the above is your main objection to the continue decision, and forcast weather was fine'n'dandy en-route (as it usually is) would that temper your critisism?
