Modern practices are different, there is now a lot more emphasis in not needlessly risking lives, especially when abandoning vessels is done by the book. But dying in the line of duty is still weirdly seen as good leadership - call it bravery, honor, commitment to the cause, gumption, etc. We mostly praise those who do, rarely criticize them for maybe sacrificing themselves and others unnecessarily. But I would think we wouldn't threaten people who don't put themselves at unreasonable risk with career consequences anymore. I guess this ejection is an example of modern marines acting with 18th century principles.
P.S. The historical record on Royal Navy's informal code of conduct in the 18th century is a bit limited. I think what I say is not disputed by many historians, but there is some room for debate.
