God is not a man that He delights in the punishment of the wicked. Calvinsts don't believe that at all.
In the passage that you quote God is simply showing the insanity of wickedness. It actually says nothing about free will. To apply it to prove free will is to make the passage say something that it doesn't.
Calvin taught that it pleased God to reprobate most of humanity, and that God is glorified by their eternal torment.
Secondly, the Bible does not use terms like "Trinity" or "free will" or "incarnation" etc... but if you know how to use language, then when God commands and urges us to repent all through the Scriptures, then that means that God gave us the choice to do so.
God will not repent for you.
God will not believe for you.
Even to those already saved and who believe, God gives them a choice to repent from sin or be punished or rejected.
Revelation 3:19-22 (NIV)
19
Those whom I love I rebuke and discipline.
So be earnest and repent. 20 Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with that person, and they with me. 21
To the one who is victorious, I will give the right to sit with me on my throne, just as I was victorious and sat down with my Father on his throne.
Revelation 2:5 (NIV)
5 Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place.
Revelation 2:16 (NIV)
16 Repent therefore! Otherwise, I will soon come to you and will fight against them with the sword of my mouth.
Revelation 2:20-22 (NIV)
20 Nevertheless, I have this against you: You tolerate that woman Jezebel, who calls herself a prophet. By her teaching she misleads my servants into sexual immorality and the eating of food sacrificed to idols. 21 I have given her time to repent of her immorality, but she is unwilling. 22 So I will cast her on a bed of suffering, and I will make those who commit adultery with her suffer intensely, unless they repent of her ways.
Revelation 3:3 (NIV)
3 Remember, therefore, what you have received and heard; hold it fast, and repent. But if you do not wake up, I will come like a thief, and you will not know at what time I will come to you.
Isaiah 1:15-22 (NIV)
15 When you spread out your hands in prayer,
I hide my eyes from you;
even when you offer many prayers,
I am not listening.
Your hands are full of blood!
16
Wash and make yourselves clean.
Take your evil deeds out of my sight;
stop doing wrong.
17 Learn to do right; seek justice.
Defend the oppressed.
Take up the cause of the fatherless;
plead the case of the widow.
18
“Come now, let us reason together,”
says the Lord.
“Though your sins are like scarlet,
they shall be as white as snow;
though they are red as crimson,
they shall be like wool.
19
If you are willing and obedient,
you will eat the good things of the land;
20
but if you resist and rebel,
you will be devoured by the sword.”
For the mouth of the Lord has spoken.
21
See how the faithful city
has become a prostitute!
She once was full of justice;
righteousness used to dwell in her—
but now murderers!
22 Your silver has become dross,
your choice wine is diluted with water.
