This question may not make too much sense. But think about this:
If a man creates a computer, using the best parts and software design with the intent of analyzing data accurately and reliably, would he also design it with the ability or freedom to 'crash' or spread viruses to other computers if it chose to?
If a man trains a dog with the intent of being a family pet, would he also give it the knowledge to kill humans or other animals?
Do you see the pattern?
If God is pure and righteous in every possible way, than why are his creations capable of evil? If God and/or Jesus created everything in their own image (that of perfection), than where did these creations (like Satan) obtain the capacity for malice? Just because a creation of God has the freedom to think for itself, it doesn't mean that it is able to do what is bad unless the knowledge of such were 'built in'? Right?
How did Satan know what evil was if he himself was a perfection creation? Why would God create angels or even humans with the ability to feel envy - knowing that this is evil (it's even one of the Ten Commandments).
Am I the only one who has ever thought the above?
