Thinking About Evil, Dabbling in Heresy ; Is Evil a Verb Rather Than a Noun?

I had a philosophy teacher once, a religious sister, who gave me high marks, suggested I might want to "go into" philosophy or theology, and said that I was an original thinker.
(How the undergraduate mind preens under such a gaze....)
I was horrified when I was older to read something I had written in that class, on which she had given me thoughtful, constructive and mostly admiring feedback, and see that what I had written was heretical, outright, no-question-about-it heresy.
And she had no problem with it !!!!!!!!

So I just wanted to say upfront that I am wary when I have thoughts on certain matters.

But a question occurs to me, would it be correct to say that Evil is "not a noun"? that is, not a thing, for God Who is all good and hates nothing He has created, and therefore never created an evil thing,

Therefore, Evil cannot be a created, (or even, perhaps, imagined,) thing,  a noun - it must be a verb, must be action.

Evil must be the doing, not the thing itself.

So the devil, a created being, was not created as an evil thing, but instead chose to engage in evil actions, to feel prideful, to disobey, and to try to provoke such actions in other beings.

Likewise, we, human beings, are never evil, (though it sometimes seems so,) we are good, but we continually are given choices, and too often choose to act in ways that are evil.
Evil is always then, an action that is a Fail, (and sometimes, quite literally, a failure to act - act in a way that would be Good, that would further God's hopes for us.)

Judas, Stalin, that bully at school - no one is created to be bad, they are all created Good by God Who is Himself all Goodness, and they choose to walk down another path.

Does any of that make sense? is it anything even approaching correct?
