Go back to the creation, of everything by God, and the darkness was divided from the light, and the darkness was not good, but the light was good.
See in John 1, how when the light shined/shines, that the darkness, does not have understanding of it, or any need for it.
Genesis 1:4 And God saw the light, that it was good: and God divided the light from the darkness.
John 1:5 And the light shineth in darkness; and the darkness comprehended it not.
Now, what that is, that God says He created there, which was the light, and the darkness, which is the peace/ the good, and the evil/not good.
Isaiah 45:7 I form the light, and create darkness: I make peace, and create evil: I the Lord do all these things.
Then evil already is known, to be darkness, opposing to light, not good, but also created by God to be in His purposes, very much from what it is divided from, which is the light and the good.
Then, Isaiah 61, reminds us of the planting of the Lord, which is trees of righteousness, to not be as evil trees, who hate the good, and who love the evil, but to be Gods remnant, loving the Lord, is to hate evil, and to love the good, and know the Lord Gods judgments.
Isaiah 61:3 To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the Lord, that he might be glorified.
Micah 3:2 Who hate the good, and love the evil; who pluck off their skin from off them, and their flesh from off their bones;
Psalm 97:10 Ye that love the Lord, hate evil: he preserveth the souls of his saints; he delivereth them out of the hand of the wicked.
Amos 5:15 Hate the evil, and love the good, and establish judgment in the gate: it may be that the Lord God of hosts will be gracious unto the remnant of Joseph.
Then, we understand how Jesus puts it to us, to make that tree/person, good, or corrupt.
Then, the generation that are evil, and do exist as evil, speak what is in their heart.
The good one, speaks out of the good treasure, and the evil one, who brings forth their evil things, did not love the good, ( only one is good and that is God) to know the righteous judgments of our good Lord Jesus Christ, and so have to answer on the day of judgement why they failed to care and love as they professed to know God. Which is another reason people are wise to be careful with our words and opinions, as only God's is correct/true, because of being the Spirit of truth.
Matthew 12:33 Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by his fruit.
34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.
35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.
36 But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.
37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
As for sin, who was first, and what it means.
The devil deceives the whole world, and some people with the devil in them, deceive others.
But the outcome describes the relevance of everyone, all go into the lake of fire, the devil, the beast, the false prophet, and who is not found written in the Lambs book of life, telling who is first matters nothing, nor who did what part, what matters is all that is evil ceases to be.
Revelation 20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
Revelation 20:15 And whosoever was not found written in the book of life was cast into the lake of fire.
