What we do know is that the Captain failed to assess the situation properly, and subsequently reacted with cowardice, leaving 4000+ people to fend for themselves. Inexcusable. He should be held fully accountable for all of the deaths. There was plenty of time to evacuate the passengers, which he squandered while saving himself.

As far as the initial event - Running aground... also inexcusible in this day and age. The Med is one of the best charted bodies of water known to man. The excuse "hit an uncharted rock" doesn't cut it. As Captain one does not make excuses and blame the charts. One takes responsibility.
