In defence of Doom, half of his intimidation is that he's flat out crazy with the voodoo--he literally doesn't care and will go to lengths sane men would balk at to make a point.
And actually, I think I had a FUG in the failure you described--I referenced it when your brother posted your sick pic. I said that's how you foiled us, you sleep with your tablet!
Every gang needs the slightly unhinged one--The Muppets had Animal for example, The Commitments had that rowdy roadie, the guy in Resevoir Dogs. Sure he's an animal, but he's OUR animal:)
