Oh, but I did address it...you are assuming once perfect, always perfect, and that is just not the case where free will is concerned...you are substituting a personal concept that goes contrary to fact..God’s intelligent creatures are granted free moral agency, the privilege and responsibility of making a personal decision as to the course they will take...Deut 30:19, 20; Joshua 24:15
It is evident that this was the case with the first human pair, so that their devotion to God could be subject to test...Gen. 2:15-17; 3:2, 3...as their Maker, Jehovah knew what he wanted of them, and from the Scriptures it is clear that he wanted, not an automatic, virtually mechanical obedience, but worship and service that sprang from hearts and minds motivated by genuine love...Deut 30:15, 16; 1 Chron. 28:9; 29:17; John 4:23, 24...if Adam and his wife had lacked the ability to choose in this matter, they would not have met God’s requirements, they would not have been complete, perfect, according to his standards...
Perfection as it relates to humans is a relative perfection, limited to the human sphere...though created perfect, Adam could not go beyond the limits assigned him by his Creator...he could not eat dirt, gravel, or wood without suffering ill effec... if he tried to breathe water instead of air, he would drown...similarly, if he allowed his mind and heart to feed on wrong thoughts, this would lead to entertaining wrong desires and finally bring sin and death...James 1:14, 15; Genesis 1:29; Matthew 4:4
As for babies who die, yes they will be given the chance to prove themselves one way or the other...in the resurrection...
I've addressed how man is made in God's image numerous times before...in our ability to exercise justice, love, and mercy, though in a limited sense, not to the extent God does...
FYI, if you disregard what Scripture has to say on these matters, you will never understand, no matter how many times it is explained to you...
