I think you will find flock that most ATCO's will be just as traumatised after the event as the pilot was.
And god forbid the end result was not good, I would imagine that they would undergo alot of self searching about their efforts dealing with the situation.
Its all a big team game up their ATC arn't your enemys or the police of the skys. They are there so everyone gets to where they want to go with the minimal of fuss as safely as possible.
I suggest you go for some beers with some and or visit a unit. They can mostly drink like fish and luv informing pilots whats involved at the other end of the mic.
