Maybe everyone does not warrant a helicopter ride......
Of course not all warrant being air-lifted. But we are often the first on scene to a casualty and neither I nor our paramedics have the gift of telepathy or x-ray vision.
If we are called to assist a casualty in a spot without an obvious landing site the choice is: do we take vaulable time to find somewhere to land and leave the paramedic to struggle to reach them by foot or do we stay at a safe height and winch?
If we have an incident whilst winching then I will be asked why I did not find somewhere suitable to land. If we have an incident trying to land in a hostile area then I will be asked why I did not winch. The casualty might have severe internal injuries - or they might have a dislocated thumb. We do not know.
I am paid to do whatever I can to rescue or deliver medical assistance to a survivor in whatever way we, as a crew, decide. In as safe a way as possible.
