In one of the 5FDP's song I always hear "Right or wrong, I can hardly tell, if I'm on the wrong side of heaven or the righteous side of hell" but in the lyrics its "wrong side of heaven And the righteous side of hell", which doesn't make sense to me, but that might be before English isn't my first language
Just my imagination, but in my head the concept that hell and heaven borders each other was a bit far fetched. With 'and' to me it feels like two are a gradient. With 'or' its different place or room, and not knowing if you are in one or the other without seeing the other, while understanding neither is a good place to be.
Guess it doesn't matter over all, the main point is same with both.
Well, he's not talking about literally directly bordering, as much as his decisions and/or heart. Basically, hard to tell whether he's making good choices (leaning bad) or bad choices (leaning good).
