As the jury here is still out, and the Pilot has already been sentenced as per the existing laws, one still needs to ponder whether it was a one-off incidence of alcoholism (binging for some reason, though highly unlikely) or is he an alcoholic?

As a psychiatrist friend of mine advised long back: alcoholism needs to be seen as an illness, like any other, which needs to be treated, without any biases and prejudices.
