Honestly - and I mean it, this is a shoot - Nash doesn't have my sympy at all. My understanding is that Tristan was living at home, under his roof. So not only was Nash a fucking idiot, and tried to force his son to quit drinking cold turkey (which is hilarious given how pompous he acts on twitter - one would think someone so "enlightened" and "empathic" would understand that chemical dependency isn't something that can just be solved by grit and willpower), he let it progress to that point in the first place. Bear in mind, in order to reach the point that you will fucking die of alcohol withdrawal, you essentially have to be perpetually drunk off hard liquor. And you have to be doing it for a while. This isn't like Tristan was knocking back 4-5 brewskis every day, it's like he was drinking rum/whisky/vodka/tequila like water, for months if not years. Somehow Big Kev didn't notice this and didn't stop it until it was far too late, and instead of doing the right thing and consulting medical professionals, he decided that he was qualified to handle it. This is in spite of him having several friends and associates who had their lives ruined by alcohol.
So if he feels like an utter failure on account of what a retard and shit father he is, and wants to take his own life so he no longer has to live with the fact that he killed his own son, then he should just fucking do it instead of fishing for sympathy on his shit podcast.
