Being as I don’t really believe in God, I’m curious to know the Catholic arguments for why God, if he exists, cannot be evil. I have heard that Thomist theology has arguments about this, but I’d like someone to explain this to me.
And for what it’s worth, I’m a non-theist, I don’t believe in the monotheistic conception of God. If such a being existed, I doubt he would be omnipotent and I would doubt he would be good.
Excellent and Challenging Question, my friend! Please consider the following personal understandings. Also, please note that the following is my first attempt at strictly defining goodness, so it will need updating.
To recognize this concept simply: Ask yourself, if you could, How would you create many free-willed beings and guide them to choose to be perfectly patient, kind, and motivated, so they may experience and spread the means to unbreakable peace, limitless happiness, and unstoppable energy, without sacrificing their free-will?
Now I will try to offer a more detailed explanation:
In order to understand why God cannot be evil, we must have a working definition of God’s purpose for us, a strong definition of perfectly good, an understanding of evil, and the big picture.
God’s purpose for us
Because God experiences and knows the awesomeness of the blessings of unbreakable peace, limitless happiness, and unstoppable energy through the free-willed powers of perfect patience, kindness, and motivation, he wants to share that with other free-willed beings.
God wants us to experience and spread the means to unbreakable peace, limitless happiness, and unstoppable energy.
To achieve this, we have to freely choose to master the Greatest Commandments as Jesus stated and demonstrated in His Crucifixion: Always be patient and kind and motivated for God with all your body and all your spirit and all your thoughts and all your will towards God, others and yourself.
From this, we can define Perfectly Good as:
Any action which achieves and spreads the means to unbreakable peace, limitless happiness, and unstoppable energy through the powers of patience, kindness, and motivation in free-willed beings.
And from perfectly good, we can define good and evil as:
Any action which does not satisfy all the factors of a perfectly good action.
As well as perfectly evil:
Any action which negates all of the factors, simultaneously, of a perfectly good action.
Now take a look at the Big Picture:
In order to create and guide free-willed beings to always be perfectly patient and kind and motivated for the desires of peace, happiness, and energy, without sacrificing free-will, God must design an incredibly sophisticated and complex system, where He would be perfectly patient, kind, motivated, just, merciful, punishing, admonishing, present, yet invisible, wise, graceful, tangible, and intangible, and many others I have yet to learn.
Why God cannot be evil.
If for any instance He was evil, He would sacrifice some element of peace, happiness, and energy in Himself, the absolute free-will of the beings He created, and/or the ability to learn and achieve the means and the spreading of the means in His purposeful creations.
Regarding your last statement: I am sorry life experiences have lead you to believe that outlook on life. If you find my understandings to be helpful, I would gladly share other understandings regarding the necessity of the Christian God of Catholicism.
