Its not a problem, I'm fine with talking about it, I've been across many such thought processes and ideas on the subject over many years, and have been fine with agreeing to disagree many times. This is just my take, summarised...
A creator being, which would necessarily exist outside of space-time, and who must therefore fundamentally have all things under potential control, and chooses when to withhold their power or influence in order to allow consciousness to have a measure of free will, can not be reconciled with any form of supernatural power that opposes it. Biblically, all references to satan or devil fit better with the simple definition of opposition or adversary, as when Jesus calls Peter satan when Peter opposes his statement concerning his death. Ideas around different forms of supernatural evil have existed across cultures for all of recorded history, and they all pretty much boil down to two simple things, (1) we humans struggle to accept full blame for stuff we do that is in some way bad, hurtful, etc, we struggle to think of ourselves ever being bad and (2) we struggle with the concept that a creator being could allow bad things to happen. It takes a bit of the pressure off if their is some supernatural being lurking in the background causing mayhem. I feel that we are better off confronting those two questions at a personal level without resorting to supernatural explanation which ultimately just doesn't square with a supernatural creator being. Sadly the introduction of a supernatural evil being into Christianity has necessarily resolved into a punitive/transactional doctrine of atonement.
I know that I'm on very unpopular ground regarding the trinity, but it just doesn't square. A supernatural being can not die, and the Bible affirms this, and also states clearly that Jesus died, which means he does not share the nature of his father. In terms of nature or being, three do not go into one, three oranges are three oranges. Examples from the natural world, besides being irrelevant when talking about a supernatural being, usually resolve to being either the 1 thing that can take different forms, or three things that can combine in some way, but in each example the nature or state of being of the things necessarily changes. The Biblical God does not change, this is stated. None of those examples from the natural world apply directly to a supernatural being. 17 people are 1 team whenever the Bulldogs start a footy game (well, bad example, they haven't played as a team for a while, but you get what I mean). In terms of where the confusion lies, in a nutshell I'd suggest that the God of the Bible and the Christ of the Bible are one in terms of purpose and outlook, rather than one in terms of nature or being. Refer to John 14-17 to find Jesus referring to his disciples (minus Judas) as being one with himself and God, contextually he is talking about purpose. Going back to atonement, it makes a lot more sense and meaning for a human non-deity Jesus to die, as that becomes at least semi-relatable and meaningful for us. If there is a supernatural creator being, while it can bring about things in the natural world, it can not change its own nature and become non-supernatural, that just doesn't make sense, and trying to make it make sense has necessarily forced theologians to go with (1) the "mystery" of the trinity as their final argument, and (2) a punitive/transactional doctrine of atonement, because a supernatural being who somehow becomes natural and dies is not relatable, there is no humanly accessible sense of giving inherent to it, and a punitive/transactional atonement is the only option left.
I've had this debate out with a catholic priest, going through loads of Bible references, and he got to the point of basically agreeing with me that he couldn't prove the trinity from the Bible. Instead he said that RCC traditions proved it, and he didn't need the Bible. He also relied on that word "mystery" a lot.
