If Paul is to be believed, "For all have sinned and do need the glory of God.” (Romans 3:23).
If this is the case, then free will is clearly not sufficient to allow us to avoid sin that supposedly condemns us to Hell, and thus the free will argument is of limited value in excusing what must, if he is held to exist, be considered God's collossal error.
Given that an omnipotent, omniscient deity must, by definition, not only be capable of creating a being that does not wish to sin and must understand the implications of not doing so, one is forced to conclude that God did indeed desire the situation some would claim we are in.
Please note: hypthetical assumptions of God's existence for the consideration of religious claims make him no more real than that other villain, Voldemort.
