Medical? That's a new one on me.
I understand different cultures and norms, and imagine he was under pressure. However, this is one area where I simply would not give in to anyone else's design of what is the right thing to do. Nope. Nope. Nope.
Call it whatever you want - it would haunt me, at least for a bit, and make me question my commitment to my sobriety (til i hopefully surrendered - again- to being powerless over alcohol *which he was by making the choice to drink*!!!). In AA, we say recovery and sobriety come before everything - EVERYTHING- else. So, that's my $0.02 - and I pray I am strong enough to make my decisions around that.
I hope he remains sober. The mental part, again, is what I would worry about - the obsession with what he did, and what he could do.
