In addition, let's face it and rightly or wrongly, Eton educates many of the future elite (CEOs and Cabinet Ministers) who will have to carry out this sort of task during their professional life, both in terms of making hard choices and in terms of taking responsibility for them and explaining them, even if hopefully in less extreme circumstances.
It would be interesting to have Eton explain what they are seeking in a 'good' answer.
If anything this 'outrage' about the question highlights the issues with social media, not Eton.
