Worse, using religion as a personal safety net for serious decision-making is a reckless desertion of leadership responsibility.
Right-minded people want leaders to take ultimate full absolute responsibility for decisions. They do not want a leader to seek refuge or personal salvation in (whatever chosen) god or heaven or a confession box.
This is an additional reason for not mixing religion with leadership and ethical decision-making: too many people simply do not accept the basic premise that a leader can delegate responsibility in such a very strange and unaccountable way.
Aside from anything else, if religion were useful in leadership and decision-making then all human organisations would be run by the clergy. Civilization tried that a few thousand years ago and it doesn't work.
