I'm not sure if that makes him a bad man.
Pretty bad in my books, and no different to someone who with a similar amount of alcohol in his system takes to driving a car/lorry/bus.
That does not make it less regrettable that he has paid the ultimate price. Just hope that his student has made or will make a full recovery.
Anyone who has this amount of alcohol in their system rieks of alcohol, pretty badly.
I don't know the circumstances of the field/club where this happened but if it was in an environment where others were around that would beg the question whether anyone was aware of this.
