So, why did your "autonomous will" chose to have a sin nature?
The same reason as you, me, and Lucifer, Adam, and every other angel and man that has sinned against God:
Isa 14:12How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High.
Jas 1:14But every man is tempted, when he is drawn away of his own lust, and enticed. Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
By choosing to lust against Him, rather than love Him with the pure heart created by Him for all angels and men.
Rev 4:11Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.
The true Creator's will is for all His creatures to please Him, and all His natural creations do so by law of nature, but the angels and men created with His autonomous will, can choose contrary to their Creator to lust and displease Him.
Deu 5:29O that there were such an heart in them, that they would fear me, and keep all my commandments always, that it might be well with them, and with their children for ever!...O that they were wise, that they understood this, that they would consider their latter end!
Only a foolish and hypocritical Christ would willingly create men with lust to sin against Him, and then bemoan himself why those same men choose to lust and sin against Him.
Ezek 18:31Cast away from you all your transgressions, whereby ye have transgressed; and make you a new heart and a new spirit: for why will ye die, O house of Israel?
And so, we see that the true Christ and Creator of all men in His image, does not Himself know why any man would ever concieve in ourselves to lust against Him to our own destruction. There is no sense in it, nor justification for it, but is only the lusting nature of sin.
What makes matters worse is proud and vain men thinking to answer the unanswerable for themselves. They proceed to make up damnable doctrines of their own to explain what God Himself cannot explain. Predeterminism and being born with lust against God is two lies that accuse Jesus Christ Himself of predestinating and creating angels and men to lust after themselves, rather than to please Him.
Jhn 1:8He was not that Light, but was sent to bear witness of that Light. That was the true Light, which lighteth every man that cometh into the world.
Not only is every man created in the good image of Christ, but every babe coming into the world is lightened to seek and love God and man. And yet for all this men still choose to corrupt their pure hearts created by Christ with lust of their. Which makes even less sense of the good and righteous Lord, faithful angels, and holy saints.
Scripture only reveals how angels and men by autonomous will choose the lusting nature of sin, but no man knows why, because God Himself does not.
