Answer and Explanation:
1. There is no "right" or "wrong" decision here since each would be to narrow to qualify the captain's actions. This is rather a case of survival and obligation (deontological) that required the captain to save the ones that he could since he could not save everyone and having some alive is better than losing everyone.
2. As hopeless as it may have seemed, the captain could have waited for a rescue team even though there was most likely none called or continued to paddle regardless but that would definitely kill them all(utilitarianism). this consequently leaves him with one choice- the one he made.
3. in the eyes of law, the captain would have still committed a crime and would go to jail since he is entitled to deciding who lives or dies and owns nobody's lives. however it is known to all and sundry that he did what he had to and may be considered right(albeit a grey area)
4.Two categories of ethical theory can be applied here. They include: the deontological viewpoint and the consequentalist theory/utilitarianism.
