Unlikely - it's definitely something you can raise in an argument about intent to get drunk and that lack of intent impacting the nature of mens rea, so it might be a mitigating factor, but either way it isn't a complete defense so you're kinda starting at negligent homicide.

The difference, of course, is I'm not actually talking about what you did, I'm talking about what makes you a scumbag. I don't think people can really be unintentional scumbags - intent is required.
