But deontology and virtue ethics are just shorthand heuristics for consequentialism, to deal with the fact that humans tend to be very bad at doing utilitarianism properly.

When the consequences are clear, and you have no other options, the rational choice is to ignore virtue ethics.

Of course, in real life, there is almost never such a clear-cut problem as this, and pat examples are often used by those who want to throw away virtue ethics out of convenience rather than actual utilitarian benefits.
