If I were given an "order" that put either myself or my crew in danger then I would advise command that I could not carry it out. I would explain the reason why I would not carry it out, and ask to discuss the situation at the conclusion of the incident. I will not knowingly put my crew or myself in danger.
As far as "moral", can you give an example ? One example I can think of would be provision of an emergency medical procedure where I neither have the training, skills, or proper equipment, ie: performing respirations without a pocket or bag valve mask.
Stay safe !!
