A lot more passengers and crew have been killed (indirectly) by fog. Are you suggesting ATCOs refuse to give a take off clearance if the destination is currently in fog, or forecast that it just might be in fog when the aircraft is due to arrive?
A lot of passengers and crew have been killed by aircraft hitting mountains. Are you suggesting aircraft are not given a clearance in mountainous area or when there are mountains en route?
Of course not. ATCOs are not employed to make these macro decisions.
