Omnipotence leads to contradictions, it is illogical.

You could ask, can God create another being more powerfull than himself ? If Yes, than he is no longer God and consequently no longer the strongest/ omnipotent, if he can't than he is no longer omnipotent as well.

One can generalize this into: Can God Do something that is impossible to do ?

This always leads to contradictions, so omnipotence is always illogical and therefore nonexistent.

What  about omniscience ? That leads to major problems as well because if God is omniscient, he already knews his own future, but then he has no longer a free will, because his own future is already set in stone. If he is able to change his future, than he was unable to predict his future correctly and therefore he is not omniscient.

So one could say, God can do everything that doesn't contradict itself.

But God in Supernatural seams to be weaker than that, destroying the Darkness would not contradict anything, considering he himself is not in some way a part of The Darkness and would kill himself by trying to destroy The Darkness.
