Never thought about it too much until recently they confirmed Em as Evil.
It'd always been obvious he was evil due to his content aka him often using knives instead of guns and getting sadistic pleasure from violence etc. rather than doing it for being a thug.
But, it's a bit of a hiccup for Em to say on the chorus of their title song...
"He's Evil and I'm Bad like Steve Segal"
I know it was just said that way to flow better probably, as it sounds better that way but still a bit of a mistake now. I never thought of it was a mistake as I'd always assumed also that they could 'switch' personas and are basically both 'bad' and 'evil' and this is just what happens when 'they' intertwine.
Also, I know you could say it kind of works due to Em using the words as adjectives rather nouns referring to each other, I think it's intended to be both, but doesn't work on the noun front, if Em is supposed to be 'Evil'.
No real point. Just noticed it.
