Nice analysis.

At first, I thought God created the Leviathans because they were prototypes. They were mistakes, failures, and as we now know, God has a thing for locking unwanted beings away (Amara, Lucifer, Gadreel).

I'm not too keen on accepting the theory that God made them in memory of his sister. God locked his sister away so he could create. He clearly could not keep both. God, at least up until he created humans, seemed to enjoy creating stuff, experimenting here and there, but when a creation fails him, he dumps it, basically.

He's not extremely compassionate. No. The God of Supernatural is pretty much a douchebag. He abandoned his sister, and never spoke of her again. He, as the Bible of Supernatural suggests, spoke ill of the Darkness (source: O Brother, Where Art Thou) and when Lucifer was locked away, he did the same (source: Hell's Angel).

True, he felt sorry for what he did, but he clearly took a stance and would not back down on his own opinion. He saw it fit to lock unwanted beings away, and never thought to apologize....until of course Lucifer threw a tantrum and Sam and Dean beckoned him to sit down and talk, and let's not forget with Amara being a threat right above their heads. ;)

As for the weapon against the Leviathans, now that never ceases to confuse me. Sera Gamble was probably hoping for something awesome, which seems to be the intention for the entirety of season 7. However, I like the idea of the weapon working simply because it contrasts the nature of the Leviathans. Also, the combined blood of various species means that these species needed to work together, something I kind of believe God always wanted in some way.
