What you are saying is the error of Origenism: apokatastasis, wherein both the just and the unjust will all go to heaven. This belief was was formally condemned in the first of the famous anathemas pronounced at the Council of Constantinople in 543: Ei tis ten teratode apokatastasis presbeuei anathema esto [See, also, Justinian, Liber adversus Originem, anathemas 7 and 9.] The doctrine was thenceforth looked on as heterodox by the Church.

The actual text in Jeremiah reads:
“The people of Judah have done what is evil in my eyes, says the LORD. They have defiled the house which bears my name by setting up in it their abominable idols.31 In the Valley of Ben-hinnom they have built the high place of Topheth to immolate in fire their sons and their daughters, such a thing as I never commanded or had in mind.32 Therefore, beware! days will come, says the LORD, when Topheth and the Valley of Ben-hinnom will no longer be called such, but rather the Valley of Slaughter. For lack of space, Topheth will be a burial place. 33 The corpses of this people will be food for the birds of the sky and for the beasts of the field, which no one will drive away. (Jer 7:30-33)
What God never commanded nor never had in mind is to offer one’s own children to be burnt before the pagan idols (the modern day equivalent are the Idols of Lust where women offer their unborn children to be slaughtered by abortion clinics of Planned Parenthood). To extrapolate such verse to mean figuratively that God does not want to send men to hell, despite their wrongdoings, is false logic. It is for the sins of Israel that God will abandon Israel even though God’s temple was built in Israel:
“Thus says the LORD of hosts, the God of Israel: Reform your ways and your deeds, so that I may remain with you in this place.4 Put not your trust in the deceitful words: “This is the temple of the LORD! The temple of the LORD! The temple of the LORD!” (Jer 7:3-4)
The greatest punishment for Israel is when God removes Himself away from Israel. In a similar way, the greatest punishment for man after death is not to be with God forever. This is greatest punishment of Hell.
God wants sinners to be saved, but not against their will. This is what God said to prophet Ezekiel:
“Only the one who sins shall die. The son shall not be charged with the guilt of his father, nor shall the father be charged with the guilt of his son. The virtuous man’s virtue shall be his own, as the wicked man’s wickedness shall be his own.21 But if the wicked man turns away from all the sins he committed, if he keeps all my statutes and does what is right and just, he shall surely live, he shall not die.22 None of the crimes he committed shall be remembered against him; he shall live because of the virtue he has practiced.23 Do I indeed derive any pleasure from the death of the wicked? says the Lord GOD. Do I not rather rejoice when he turns from his evil way that he may live?24 And if the virtuous man turns from the path of virtue to do evil, the same kind of abominable things that the wicked man does, can he do this and still live? None of his virtuous deeds shall be remembered, because he has broken faith and committed sin; because of this, he shall die. (Ez 18:20-24).
