Satan was going about to see who he could devour...who/what he could steal, kill or destroy.<quoted text>
Why does Satan appear a few times in the OT as a member of God's heavenly court?
To have free will, you must have the ability to commit an evil act.
Otherwise, you're certainly not free and you definitely don't have free will.
True and we have free will. We are accountable for the words we say and our actions.
