Free moral agency is taught in the Scriptures. But the problem is that you're ignoring that it not the "nature" of man that predetermines him to evil. It is God's decree that does so. Calvin, the "hyper-Calvinist" said that, btw. I already quoted that passage. But here is another one:

Quote
]1. THE human mind, when it hears this doctrine, cannot restrain its petulance, but boils and rages as if aroused by the sound of a trumpet. Many professing a desire to defend the Deity from an invidious charge admit the doctrine of election, but deny that any one is reprobated (Bernard. in Die Ascensionis, Serm. 2). This they do ignorantly and childishly since there could be no election without its opposite reprobation. God is said to set apart those whom he adopts for salvation. It were most absurd to say, that he admits others fortuitously, or that they by their industry acquire what election alone confers on a few. Those, therefore, whom God passes by he reprobates, and that for no other cause but because he is pleased to exclude them from the inheritance which he predestines to his children. Nor is it possible to tolerate the petulance of men, in refusing to be restrained by the word of God, in regard to his incomprehensible counsel, which even angels adore. We have already been told that hardening is not less under the immediate hand of God than mercy. Paul does not, after the example of those whom I have mentioned, labour anxiously to defend God, by calling in the aid of falsehood; he only reminds us that it is unlawful for the creature to quarrel with its Creator. Then how will those who refuse to admit that any are reprobated by God explain the following words of Christ? “Every plant which my heavenly Father has not planted shall be rooted up,” (Mt. 15:13). They are plainly told that all whom the heavenly Father has not been pleased to plant as sacred trees in his garden, are doomed and devoted to destruction. If they deny that this is a sign of reprobation, there is nothing, however clear, that, can be proved to them. Book III, ch. 23, paragraph 1.

John Calvin, Institutes of the Christian Religion (Bellingham, WA: Logos Bible Software, 1997).

In short, God is the cause of reprobation, not some impersonal "nature" in man. Luther and Calvin both denied that libertarian free will existed in Adam before the fall, although Adam was not yet a "slave" to sin.

For "who has known the mind of the LORD that he may instruct Him?" But we have the mind of Christ. (1 Corinthians 2:16 NKJ)
