Hello I've been following the show since from the start, and something has been gnawing at me for a while about the plot at the end of the last season, when Castiel became God by absorbing the souls from Purgatory.
My question is why haven't anyone else done it? It seems such a straightforward way to becoming powerful, that I find it hard to believe that no one else has attempted it.
Crowley estimated there are 30-40 million souls in Purgatory. That number seems like a minuscule amount when you consider that there are 5-6 billion souls on Earth alone and souls have been going to heaven and hell since forever.
So why haven't someone just taken Heaven or Hell's soul and be "God" too? I'm just wondering if anyone have had similar thoughts about this.
