Yes, evil is only a man made construction attributed to gods, and devised by evil men who are themselves, deceived by their own evil thoughts and actions. James 1:13-16
I feel like I need to address this again as it is definitely the most controversial statement of your view on this issue. I tried to approach this from a purely logical perspective initially, but let’s try it with a little help from scripture.
You claim evil does not truely exist, except that it is just a construct created by evil men who commit evil. Ignoring the previously mentioned logical issues with this, let’s examine the origin of evil itself.
In Genesis, we find Adam having been placed in the garden and commissioned to tend it:
Genesis 2:15
And the Lord God took the man, and put him into the garden of Eden to dress it and to keep it.
Eve has not been created yet, and man has not yet fallen when God issues his first command not to do something, which is:
Genesis 2:16-17
And the Lord God commanded the man, saying, Of every tree of the garden thou mayest freely eat: But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
Here, I think, is where your argument falls apart scripturally. God directs Adam not to eat of the tree of the knowledge of good and evil. Interestingly, the verse implies that God himself has named the tree, not Adam. This provides solid evidence that evil existed prior to man’s fall and that it is not something created by man.
Later we read of the Devil’s role in the account of the fall:
Genesis 3:1-3
Now the serpent was more subtil than any beast of the field which the Lord God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden? And the woman said unto the serpent, We may eat of the fruit of the trees of the garden: But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
We see clearly a special entity craftier than any animal made. Also, the serpent tempts or coerces Eve to eat of the fruit, and she protests at first and eventually gives in and shares the fruit with her husband Adam.
Lets travel back though, to the serpents argument:
Genesis 3:4-5
And the serpent said unto the woman, Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
The serpent does not force the fruit on Eve or Adam, they are responsible before God for having eaten. Nevertheless, the serpent twists God’s command and tells them they will not die when they eat it. Then, he explains that once they eat it, they will be like God in that they will now know the difference between good and evil. These are lies and deceptions that make evil appear to be good! That is what Satan does and is his role in evil.
Lastly, Satan’s half truth is correct. Suddenly Adam and Eve are aware of evil and good:
Genesis 3:7
And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.
From these verses, we understand that Satan is a tempter and deceiver and interacts with man to man’s detriment, and that evil predated man’s fall. It is a simple matter of accepting what the scriptures say and not trying to read something else into them.
