The Christian idea of Satan completely destroys the idea of a benevolent, multi-omni God as described by Jws and some Christian subsets.
As anyone that has done even the slightest study on psychology knows, "Free Will" is a perceptive illusion. We only "feel" like we are in control of things because we don't have the brainpower or history to trace all of our mental influences.
In reality, people are "programmed" based on two things:
1) Our biological makeup, and
2) How that combines with what we are exposed to through life
Because no person has no control over their biological makeup and (especially) their early exposure, they cannot have true free will because of this. The person we become is out of our control. We only "feel" that we do, because once our base makeup is formed, internally, it "feels" like we have choice from within. If a brain or computer was powerful enough, it could accurately predict any choice we would make by factoring in our biology + the stimuli we receieved (ie. an all-knowing God would be able to predict this).
According to JW and some Christian mythology, God created an angel that "chose" to go against God.
However, God created (a) that angel's makeup, and (b) the environment that angel was placed into, so there's no avoiding the fall is directly God's fault, since he made the angel exactly what he was. There is absolutely no way around this.
This was something I brought before parents and the elders when I was a teen and still attending before I "faded." The conversations basically went:
"You accept that people are a combination of their environment and their biology, correct? We aren't blank slate souls all born into the same conditions - our "person" is formed by our brain chemistry and our environment, right"
- Yes.
"Who created the brain chemistry and bodies of Adam/Satan?"
- Jehovah
"Who created the environment?"
- Jehovah
"So how could they sin?
- They had free will and chose to!
"But you just said that their decisions are based on aspects out of their control, as they are determined by creative and environmental factors!"
- *Strains to think. Gets mad. * What you're saying God is imperfect now?! He gave us all free will!
"-YOU- just said that. You admitted it two seconds ago! What other magical factor is there that exists outside of what was stated that causes us to be what we are?!"
- We have free will! (Shuts conversation down)
...it was one of the most highly frustrating things, even as I was a kid, and one of the first times I noticed cognitive dissonance in action.
