It is ordained, not determined. There's a difference. You can choose something of your own will only if God ordains it to be so, but God didn't make you do it. Joseph's brothers sold Joseph into slavery of their own (fallen) free will. But God meant it to happen. It says so right in the text.
playing the semantics game here is RC below:
God wills all things that come to pass…God desired for man to fall into sin. I am not accusing God of sinning; I am suggesting that
God created sin.”
Calvin:
“The hand of God rules the interior affections no less than it superintends external actions; nor would God have effected by the hand of man what he decreed,
unless he worked in their hearts to make them will before they acted.”
AW Pink below :
“Plainly it was
God’s will that sin should enter this world, otherwise it would not have entered, for nothing happens
except what God has eternally decreed. Moreover, there was more than a simple permission, for God
only permits things that fulfill his purpose.”
And Piper :
“God brings about all things in accordance with his will. It isn’t just that God manages to turn the evil aspects of our world to good for those that love him; it is rather that
he himself brings about these evil aspects… This includes God’s having even
brought about the Nazi’s brutality at Birkenau and Auschwitz as well as the terrible killings of Dennis Rader and
even the sexual abuse of a young child.”
And Cheung :
“God controls everything that is and everything that happens.
There is not one thing that happens that he has not actively decreed – not even a single thought in the mind of man. Since this is true, it follows that
God has decreed the existence of evil, he has not merely permitted it, as if anything can originate and happen apart from his will and power. Since we have shown that no creature can make completely independent decisions, evil could never have started without God’s active decree, and it cannot continue for one moment longer apart from God’s will.
God decreed evil ultimately for his own glory, although it is not necessary to know or to state this reason to defend Christianity from the problem evil.”
“Those who see that it is impossible to altogether disassociate God from the origination and continuation of evil nevertheless try to distance God from evil by saying that God merely “permits” evil, and that he does not cause any of it. However, since Scripture itself states that
God actively decrees everything, and that nothing can happen apart from his will and power, it makes no sense to say that he merely permits something –
nothing happens by God’s mere permission.
