"The Darkness should be able to destroy or consume all the souls in existence with a thought"

But if thats true, why haven't Darkness done that? Ruining God's creations is probably thing that Darkness want most.

Why wait if Darkness really is that powerful ?

Isn't that after all what Darkness "does" ? Death said: "The Darkness is destructive force that nearly obliterated anything in its path, causing nothing but chaos and destruction.".

So far Darkness only created Rabids (if we don't count Amara), which were beaten pretty easily by Dean and Sam.

In last episode (11x06), Amara said follow things:

"Soon, I'll be strong enough." "Settle an old score -- the oldest score."

This most likely means payback to God for putting Darkness to "prison" (or early betraying by starting war with Darkness in first place). If Darkness created Amara for that mission, why couldn't Darkness made Amara like million time stronger than she is now ?

Reason is obvious: Because Darkness isn't that powerful. At least not yet. Could also be that God is using his power to stop Darkness using her power to destroy Earth and other realms.
