You claim Jesus can't be God unless humans are devils? No connection there whatsoever.
Devils are not "humans." They are unseen adverse spirits, duly noted prior from Eph. 2:2 as an example. No one "sees" Satan do this for another example: Mark 4:15.
Jesus did address, openly, devils in mankind and 'cast them out' of mankind (in some cases, in other cases NOT, with Judas for example), showing and proving they are not the same entities as mankind. Too many scriptural citings to list, but Luke 8:30-32 is one of the more dramatic examples of "many" devils having "entered" into one man. Luke 11:24 is another example. So is 2 Cor. 12:7 or 1 John 3:8.
When we have a very OBVIOUS devil to observe there is no excuse to get the parties confused making Judas the same as Satan who "entered" Judas.
Luke 22:3
Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve.
John 13:27
And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
Though I disagree with JLB on a lot of his positions at least he's figured out that Satan speaking from Peter didn't make Peter Satan, Matt. 16:23, anymore than it made Judas Satan for essentially the same activity of Satan and Peter as Satan and Judas above.
Both events are examples of the reality of Mark 4:15.
You can believe Jesus was a man and the Son of God, but you cannot believe Judas was a man and a devil? I don't see how you can believe one thing and not the other.
Judas was not some unseen entity or a spirit. Nevertheless he was a devil. To those who had believed in him Jesus said, You are of your father the devil. So it depends on your Father. If God is your Father, then you are his son. If the Devil is your father, then you are his son ie. a devil.
