As long as you ignest methanol with enough ethanol mixed in, it's not lethal. You would have to separately capture the small amount of stuff coming out before the "heads" to make deadly methanol. Soundslike this could happen only if you make an industrial quantity batch, and are completely reckless about the basics.
I don't know Popcorns case in detail but if the assault you listed was in self-defense every thing you list is illegal but not wrong.
All alcohol is toxic. Exchange and consumption are consensual, that's what matters.
