I am going to give an answer from a scripture-based Catholic point of view. **The devil had no intention of making Adam fall. His full aim was to deceive Eve and Eve alone.** This is the reason why Bible says that "Adam was not the one deceived; it was the woman who was deceived and became a sinner."<sup>1 Timothy 2:14</sup> In revelation we know that all angelic beings' minds (including devil's) was illuminated by God with the plan of salvation, that God will be born of a woman: The woman will bring forth a child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.<sup>Rev 12:5</sup> This is clear that a human being who is less than angelic beings, will be brought to higher glory than them. This human was to be brought forth by the woman. And the devil had a problem with this. He knew that the woman was the central figure to this plan, and bringing down the woman will spoil the entire plan. The vision clearly states that the dragon was chasing the woman to kill her, seek his revenge and spoil God's plan. Rev 12:13-16 narrates his attempt. This vision happened before the creation of the material world. After the creation of the material world, the Devil acted as soon as he saw a creature (Eve) who looked like in the vision he had before the fall, and decided to tempt her. The problem is he chose the wrong woman. Also note that the woman in the vision (before the fall) was timid and fearful. She runs for her life and earth has to protect her. The execution of devil's plan had cost the whole of humanity, not just the woman. So God cursed the devil/snake differently than He did with Adam and Eve. He foretells the victory of the woman and her seed and that they both will hate him. This shows that the woman will no longer be timid, but victorious. Remember the war in heaven is not between God and the devil, but rather between creatures. This is why Catholics believe that of all creatures Mary is the one Satan hates the most. His hate for all other creatures put together will not be equal to the amount of his hatred of Mary. Because when he sees Mary, he sees his loss and his doom.
