If the crew had been train and if the bridge crew had done their duty I see little reason for anyone to had lost their lives in this grounding.
Hell most of the ship is still above water.
But bodies were found in the part of the ship that is still below water, and there are reports of bodies still in the water. And several crew members are among the dead and missing.
It's not just what the bridge crew did or didn't do. There were 4200 passengers on a ship that had a power failure, went into darkness, began taking on water, and began tilting, all relatively quickly. There are limits to how fast a crew can locate those who couldn't make it to the deck and lifeboats, and how fast you can fill and lower those lifeboats and get people off the ship. And passengers were panicking, and agitated, and frantic, and not always orderly, and speaking different languages, adding to that difficulty.
It's glib of you to say, "I see little reason for anyone to had lost their lives in this grounding," but you weren't there and you don't know what actually went on. Some loss of life in this situation might have been inevitable once the evacuation order and the distress call for rescue help were delayed, because there were just too many people to get off the ship and not enough time to do it in a more orderly way that might have saved everyone.
I think the crew has to be given credit for all the lives that were saved.
