The devil made me do it
There is no more quintessential shifting of blame, shirking of responsibility, laying of fault at the foot of a convenient scapegoat than the devil made me do it.
Think about it: He created the world and called it good. But even a flame burns itself out in search of darkness. Everything has its opposite, even existence; although, full disclosure, we, He and I, have never experienced its opposite.
He created all that is visible to the human eye, and when his creation disappointed, He could not blame himself (God forbid...so to speak), and so, he revealed me. I mean, the Bible is His word, yes? So, He blamed Eve's choice (original sin indeed; more like original scapegoating) on outside influences rather than an intrinsic flaw or design defect.
Deflect.
Consider this: if humanity has free will and makes choices considered not good (although I have to say that which is defined as good seems to live in a fluid, murky place), if you blame humanity, ultimately, you blame that which created humanity for having produced something at best, imperfect.
Similarly, if you say all is predetermined, that from the moment He conceived of Creation, He knew everything and everyone that would ever be until all that is returns to what it was pre-Creation, then who else can one blame other than the Creator?
The devil, of course.
And so, we have the devil made me do it.
Which, in the end, is all the same really.
As I said, everything in existence has its opposite. We, He and I, are the epitome of that duality. Two sides of the same coin, we are. The yin to his yang. The darkness he fills with light...or which douses it every now and again.
Where He is so too am I, the face he prefers to deny and call other.
It just makes Him and, I dare say, you, feel better to say the devil made me do it.
I don't mind.
