(1) Adam was our representative. ( Catholics and Protestants)
Our Creator made Adam perfectly, but only as a creature.
And Adam is our object lesson, showing how even God's own perfect creation is so able to fall to Satan. Because only God is good, only God is able to keep from changing to evil. So, Adam proves how any of us need Jesus. And we, of course, have been not at all close to perfect like Adam and Eve were, before their fall; so there is no way we without Jesus have a chance.
So, if Adam is our representative, he represents how any of us can fail.
Only Jesus could be the first to live and love perfectly on this earth. Plus, Jesus is able to change us so we live and love more and more maturely like Jesus. So, it is wise to point to how God is so good, that He sent His only begotten Son Jesus to reach us and share with us and so suffer and die for us.
(2) Adam's sin didn't incriminate us but did have horribly painful consequences for our world. (Orthodox).
Our Apostle Paul says there is "the spirit who now works in the sons of disobedience", in Ephesians 2:2. This evil spirit of sin existed before the fall of Adam and Eve, and my opinion is that this evil spirit of Satan's kingdom corrupted Adam and Eve to become disobedient. Before they disobeyed, they were perfect as creatures; but then Satan's evil spirit changed them to become disobedient. And this evil spirit has been passing on, ever since, to children of humans.
You can see how it is natural for a child to be mainly or only concerned about one's own self, and pleasure can be the priority of a child. This is how Satan's evil spirit makes humans selfish. This can show from birth, even.
Therefore, every human has needed to be turned "from the power of Satan to God," as Jesus said Paul would minister for people to be changed > Acts 26:18.
I suppose a third view exists.
(3) Adam never literally existed. Biologically we evolved into this horrible world.
The spirit of Satan's kingdom exists > "the spirit who now works in the sons of disobedience" > Ephesians 2:2. In order to be saved, a person needs to be delivered from the power of Satan's kingdom, into God's kingdom. So, this does not take only a belief change or only theoretical correction of how people think about God.
All three views unacceptably extrapolate to a God who is hardly the epitome of kindness and thus is either comparatively evil or totally evil. After all, given the power to create a world, any of us would have exercised more kindness than 1,2, and 3.
Any of us would have helped to crucify Jesus. Look at how even those Jewish mothers and fathers cursed their own children with the blood of Christ > Matthew 27:25. Mommies and daddies so hated Jesus, because of their sin through Adam and Eve, that they cursed their own children with the blood of Jesus. This is how Satanic humans can become, because of the evil spirit > Ephesians 2:2 > of Satan's kingdom. But humans usually are not so obviously behaving in an evil way, because they are busy with getting what they want in their lives. But if you somehow threaten or mess with what a human in sin treasures, then is when that person can get to acting like a major lunatic.
So, it is very unwise to boast or claim that humans would do things better than God.
What is kind is how God is processing the evil spirit to the flaming sewer which burns with fire and brimstone. The spirit of evil is a reality, and God has been doing what is realistic, by having Jesus die for our sins and processing evil to the flaming sewer. We now can be with Jesus, in His almighty immunity to howsoever evil would effect and control us . . . and our attention. Right in this evil world, we can be safe while learning how to love with Jesus and one another as God's family > this is kind, and so more and better than what any human without Christ has been doing or trying to do. And this is now > including how Jesus gives us "rest for your souls" >
"'Come to Me, all you who labor and are heavy laden, and I will give you rest. Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.'" (Matthew 11:28-29)
No human can give anyone, not even oneself, rest for one's soul . . . and this right in the presence of evil and any enemies > "You prepare a table before me in the presence of my enemies" (in Psalm 23:5). Humans can tend to try only to change circumstances and social status and treatment, but deeply they do not have the almighty safety and rest of God's love. So, they are not being kind, at all, merely by changing outward things and re-explaining God's word. They themselves are the ones who need to be changed!!
The obvious solution is that God only made one material soul named Adam (even Eve was a physical subsection extracted from Adam's ribs). After Adam sinned, God removed most of that material soul from his body unto a place of suspended animation. When each of us was later conceived, God mated a separate microscopic portion of that sin-stained soul to each of our bodies. In other words, YOU are 100% Adam (not a mixture). YOU are the one who freely chose to eat of the forbidden (although none of us currently remember doing so).
We in Jesus are no longer children of Adam.
"Therefore if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new." (2 Corinthians 5:17)
If I am a new creation in Jesus; it is not wise to say I am a child of Adam and his sinning, or else you are saying I am a child of Satan!!
P.S. This remedy isn't a complete solution to the problem of evil. The larger issue is, why would a perfectly kind God allow temptation in the first place? Historically the church has made a pretense of providing satisfactory answers but has patently failed. Problem is I can't discuss this aspect on the current forum as my solution falls under Controversial Theology.
God is not theoretical and idealistic. God knows what reality is. God knows there is "the spirit who now works in the sons of disobedience" (in Ephesians 2:2). And God has proven Himself against any and all evil.
In His kindness, God is processing evil to the flaming sewer which burns with fire and brimstone. And there are evil beings like Satan and his fallen angels and selfish humans who are sewer buckets of Satan's filth of corrupting lusts, unforgiveness, hate, wrath and anger, fear and anxiety and worry, hurry, arguing, complaining, and bitterness. Sewer buckets of this evil and vile filth are helping to transport that nasty stuff to the flaming sewer.
Humans in sin, then, are acting as sewer buckets of Satan's filth of unforgiveness and dominating and dictatorial drives for pleasure, and how they can react bitterly and negatively to not getting their own way. But God in His kindness is giving us time so people can defect to Jesus, from Satan's kingdom.
Therefore, do not be a bucket of the filth of sin, or you could go where it is going. Jesus has suffered and died, in order to deliver any and all people from Satan's power and sin. And we can enjoy rest with Jesus, instead, in God's family caring and sharing and tenderly affectionate love.
So, instead of looking for explanations and in haste inventing what we can make up, we need to follow the example of Jesus.
"And walk in love, as Christ also has loved us and given Himself for us, an offering and a sacrifice to God for a sweet-smelling aroma." (Ephesians 5:2)
By the way, people knew Jesus; they had His proof right in their faces; but still they wanted to kill Him. So, instead of seeking or pretending to seek explanations, seek to follow His example.
