Lest I am in any way misunderstood, let me say that I have the utmost respect for the pilots, medics, flight nurses, EMT's, mechanics and support staff that are all focused on the same thing - flying the mission safely.
It is usually not the decision of any of those folks to choose a mission - the only decision they get is whether to launch it, and even then only if the WX is near minimums, or there is an issue with the aircraft.
