Another point

I have not, of course, disproved the devil, or a prime evil, at all at this point. I have only noted the problems with the Lucifer story. So I will switch to a more philosophical approach.

If God is omni-benevolent (omni meaning all, completely, entirely, perfectly, etc) and if everything in the universe (or multiverse if one beleives in multiple dimensions) has an equal and opposite, then it would follow that there is an omni-malevolent force. However, omni-benevolence is very hard to describe. It requires that God is, in every possible way, good, wishing of good things to happen, and willing to help. If God is also omnipotent, that is, having limitless power, then it would follow that God will make sure everyone and everything is in a state of well-being. It takes only a quick glance at the state of the world to know that this is not reality. However, this does not disprove anything. It merely means that either God is not omni-benevolent, God is not omnipotent, or there is some force of equal potency which is preventing God from acting in his benevolent fasion.

The last of the possibilities does not necessitate an omnipotent, omni-malevolent force. Other such things as the rule of free will are also acceptable reasons for God's lack of intervention. This would mean that free will is a higher priority in God's mentality than his benevolent nature, for which we could ask why, but that is not the subject of my arguement.

If God is not omni-benevolent, then it would follow that there is no omni-malevolent force. If God in not omnipotent, the opposing force would not be either. If the reson for God's lack of action is for the sake of free will, then the opposing force is not nessicary for reasoning, but goes against the action-reaction rationalle.
