God wants humankind to reign with Him. (Genesis 1:26-29; Revelation 22:5) It is what we have been created to do.
In order to have personhood and to reign (exercise authority), one has to have a will (the power of creative action). In exercising that will, we have the ability to rebel against the authority of God (sin).
Your question overemphasizes something - you characterize God's creation of humankind as a failure. It is not a failure, it is becoming, and will become, a magnificent success! Sure, humankind has sinned against God and each other - and that is truly a horrible and destructive thing - but God can handle it. God is redeeming all of the evil that humankind has done through Jesus. Of course, only though who enter into the Kingdom (Reign) of God will be sustained eternally (have eternal life) and the rest will perish (John 3:16).
There is coming a day when all of humankind will have gone through the refiner's fire and will be free moral agents who have permanently and intentionally committed themselves to the reign of God and will reign with Him forever. Those who reject God's offer will have already perished. Justice will reign and evil will simply not exist for all of those who commit evil will be consumed in the Lake of Fire (Revelation 21:8).
Great response.
I agree. Consider:
But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man, that thou visitest him? Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands: Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him. Heb 2:6-8
However:
But now we see not yet all things put under him. V8
What man? The man in the image of whom?
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. 1 Cor 15:45,46
Man in the image or the first man Adam, or in the image of the resurrected last Adam, assuming, "afterward," is speaking of the resurrection of Christ the only man born of woman to have died and resurrected to die no more.
To rule as Baptist Believer spoke of would one must need to be, born as the first man Adam and also must need to be born again in the image of the resurrected Christ?
The kingdom of God?
