Only God has free-will.

Try looking at it from the following perspective from Blessed Aquinas that is backed up by Scripture

That it is reasonably reckoned a Man's own Fault if he be not converted to God, although he cannot be converted without Grace

SINCE no one can be set on the way to his last end without the aid of divine grace, or without it have the necessary means of reaching that end, as are faith, hope, love and perseverance, some might think that man is not to blame for being destitute of these gifts, especially seeing that he cannot merit the assistance of divine grace, nor be converted to God unless God convert him: for none is responsible for that which depends on another. But allow this, and many absurdities follow. It follows that the man who has neither faith nor hope nor love of God, nor perseverance in good, still does not deserve punishment: whereas it is expressly said: He that believeth not the Son shall not see life, but the wrath of God abideth on him (John iii, 36). And since none reaches the end of happiness without the aforesaid endowments, it would follow further that there are some who neither attain to happiness nor yet suffer punishment of God: the contrary whereof is shown from what will be said to all present at the judgement of God: Come . . . . possess ye the kingdom prepared for you, or, Depart . . . . into everlasting fire (Matt. xxv, 34-41).

To solve this doubt, we must observe that though one can neither merit divine grace beforehand, nor acquire it by movement of his free will, still he can hinder himself from receiving it: for it is said of some: They have said unto God, 'Depart from us, we will not have the knowledge of thy ways' (Job xxi, 14). And since it is in the power of free will to hinder the reception of divine grace or not to hinder it, not undeservedly may it be reckoned a man's own fault, if he puts an obstacle in the way of the reception of grace. For God on His part is ready to give grace to all men: He wills all men to be saved and to come to the knowledge of the truth (1 Tim. ii, 4). But they alone are deprived of grace, who in themselves raise an obstacle to grace. So when the sun lights up the world, any evil that comes to a man who shuts his eyes is counted his own fault, although he could not see unless the sunlight first came in upon him

A very interesting post by Aquinas. But I would suggest looking more closely at what he is saying:

...To solve this doubt, we must observe that though one can neither merit divine grace beforehand, nor acquire it by movement of his free will, still he can hinder himself from receiving it: for it is said of some: They have said unto God, 'Depart from us, we will not have the knowledge of thy ways' (Job xxi, 14). And since it is in the power of free will to hinder the reception of divine grace or not to hinder it, not undeservedly may it be reckoned a man's own fault, if he puts an obstacle in the way of the reception of grace.

I find this a remarkable statement. Why would man hinder himself from grace? If one is face with a choice between heaven and hell, unfetter by everything around him so that he is capable of making a rational decision between going the heaven or going to hell, then why would they choose hell? Personally, I don't know of anyone who sat down and "rationally" decided one way or the other. And I would say this includes Adam. Do you believe Adam made a rational decision? This certainly doesn't fit into the gospel experience.

As far as Aquainas's text (Job 21:14), please not the context of Job's speech:

Job 21:1 Then Job answered and said: Job 21:2 "Keep listening to my words, and let this be your comfort.

Job 21:3 Bear with me, and I will speak, and after I have spoken, mock on.

Job 21:4 As for me, is my complaint against man? Why should I not be impatient?

Job 21:5 Look at me and be appalled, and lay your hand over your mouth.

Job 21:6 When I remember, I am dismayed, and shuddering seizes my flesh.

Job 21:7 Why do the wicked live, reach old age, and grow mighty in power?

Job 21:8 Their offspring are established in their presence, and their descendants before their eyes.

Job 21:9 Their houses are safe from fear, and no rod of God is upon them.

Job 21:10 Their bull breeds without fail; their cow calves and does not miscarry.

Job 21:11 They send out their little boys like a flock, and their children dance.

Job 21:12 They sing to the tambourine and the lyre and rejoice to the sound of the pipe.

Job 21:13 They spend their days in prosperity, and in peace they go down to Sheol.

Job 21:14 They say to God, 'Depart from us! We do not desire the knowledge of your ways.

Job 21:15 What is the Almighty, that we should serve him? And what profit do we get if we pray to him?'

Job 21:16 Behold, is not their prosperity in their hand? The counsel of the wicked is far from me.

These are the wicked. Those people who have no desire to serve God. They do not answer the external call of God so there is no internal call. I believe Aquinas completely misread this section of Job. I would suggest comparing against Paul's writings:

1Co 1:25 For the foolishness of God is wiser than men, and the weakness of God is stronger than men.

1Co 1:26 For consider your calling, brothers: not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth.

1Co 1:27 But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong;

1Co 1:28 God chose what is low and despised in the world, even things that are not, to bring to nothing things that are,

God gives us this answer to Job's question many years later. He chooses (yes chooses) that what is low and despised to make His riches known. So we shouldn't get a big head.

I would have liked to have heard an explaination from Aquinas on 1 Cor 1:28. Had he been an Augustinian and not a Dominican he might have done better. Perhaps it was his nickname "Dumb Ox" that stigmatized him. :O)
