He was most likely both drunk and high, based on the whole "possession of drug paraphanalia" charge.

Regardless, in my opinion, this sort of irresponsibility needs to be punished. He'll feel horrible and guilty and whatnot for the rest of his life, sure, and he'll have plenty of time to reflect on it in jail for hopefully years.

Drinking a crazy amount still doesn't usually lead to hanging people out of windows for fun. There were probably illegal drugs involved in this death, and if that's the case, this man deserves many years in prison for that alone.

I usually can't find pity for this kind of stupidity. This is all assuming that it was an accident, though. Continuing on this assumption, if she was also drunk and/or drugged up enough and let him do this, that's her own fault as well. In the guy's defense, if it was an accident, the girl is equally to blame.
