In parochial school we were taught that God created all things and that included the devil. I can't remember the exact reasoning of this action but to Catholics it was supposed to make sense.. It never did to me. What are your thoughts on the subject? Did God create the devil? Why?
Here's one answer:

4. But since He created Lucifer, isn’t God really responsible for his sin?
Answer: Not at all. God created Lucifer a perfect, sinless angel. Lucifer made a devil of himself. Freedom to choose is a cornerstone principle of God’s government. God knew Lucifer would sin when He created him. If at that point God had refused to create Lucifer, He would have been repudiating one of His own characteristics of love; that is, the freedom to choose.
Freedom of Choice Is God’s Way
Knowing full well what Lucifer would do, God still created him. He did the same for Adam and Eve—and for you! God knew before you were born how you would live, but even so, He permits you to live so you can choose Him or the devil. God is willing to be misunderstood and falsely accused while taking time to allow every person to freely choose whom he or she will follow.
Only a Loving God Would Risk Granting Full Freedom for All
This glorious and crucial gift of freedom could come only from a just, transparent, and loving God. It is an honor and a joy to serve such a Creator, Lord, and Friend!
