In fact, this verse argues the exact opposite of what you are putting into it:
"Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: (For until the law sin was in the world: but sin is not imputed when there is no law. Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come. But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many" (Rom 5:12-15)
So if death enters "by sin," but if there is no law there is no sin, why then do people die who have no law? The "neveretheless, death reigned from Adam to Moses," would imply that there must have been some law prior to the coming of Moses of which they were all being destroyed for. And that can only be the "offense of one" which was being imputed upon all the descendants of Adam. This also does not speak of merely having the "ability" to sin, but condemns them for "all have sinned," including children, which can only be true if all humanity was involved in the sin of Adam.
That is one of the penalties of the original sin of Adam and Eve...Whether we sin or don't sin, we still have to work and die (and then the judgment)...The sin or no sin question determines our destination after death...
All souls who have inhabited a body proceeding out of Adam's DNA must suffer physical death; that is, separation of the soul and spirit from a no-longer-functioning meat body system. That is the kind of death that the new-born infant must suffer sometime after birth. He is born to die. Even Jesus was. That is the kind of death brought in by Adam's sin.
But Adam's sin also caused spiritual death--the inability of man's spirit to communicate with God's Spirit. Unless that baby is rescued, he/she will the suffer Eternal death, the Lake of Fire.
When sin is not imputed, as with the babe who is not conscious of the law, the babe might have to experience an early physical death, but its original sin will be overlooked, and its soul and spirit will be given both Eternal and spiritual life: he will come under The Blood.
Neither the blood of bulls, nor of goats, nor of the water of human visible baptism can take away sins. Only Jesus' Blood can do that. And after being made aware of sin, of righteousness, and of imminent judging by God, the person who fails to appropriate Jesus' work and resurrection power will also die physically, remain spiritually dead, and be given over to Eternal but conscious death, ultimately in the lake of fire.
One who responds to this awareness by admitting his depravity and casting himself on God's unfailing mercy will experience the graceful spiritual covering and cleansing of Jesus' blood shed for him, and will have Jesus' righteousness imputed to him, and will pass immediately into spiritual life and communication with God and His Son through the Holy Spirit, will receive Eternal, abundant Life immediately, never to cease; and at an appropriate time chosen by The Father, will also have a new never-dying flesh body to house his/her preserved soul and spirit.
And in that Paradise, there will be individuals who, as babes, never committed sin and to whom the original sin transmitted with their temporary tent of Adam's flesh was never imputed to their account by God.
In this all, the proper use of water baptism, as a visible external announcement of an internal change by faith in Christ and His Blood, has no effect one way or the other. It only relates to the authorized enlistment of a person into His Church and into His service while on earth.
Water baptism can never take away sins. To think otherwise is both intellectually and spiritually foolish.
You need to reread Genesis 1-3. I’d say that less than 1 in 1000 Christians understands the implications of the Fall. Your comments seem to indicate a fundamental misunderstanding. Keep in mind that a sin is a transgression is a missing of the mark.
