Endless infinite tortures are deserved for any single sin?
No sir, only for the unforgivable sin, rejecting YHWH as GOD by putting your faith (an unproven hope) in the idea that HE was a false god and a liar driven by the evil need to manipulate people to worship him and rejecting HIS claims of salvation to be found only in HIS Son as more lies because there was no such thing as sin and no hell either.
The elect, those who accepted HIS claims to be our creator GOD by faith and who put their faith in the promise of salvation found in HIS Son, were chosen, elected, to be HIS bride in the heavenly state but those who rejected HIS divinity and salvation, became unforgivable and eternally sinful, fit only to be banished to the outer darkness as never able to fulfill HIS reason of our creation, the heavenly marriage.
As soon as our choices were finished as to where we would put our faith, as the most righteous who cannot abide evil, HIS next order of business would have been to call for us to come out from the non-elect reprobate so they could be judged. Some of the elect rejected this call, idolizing their reprobate friends over their GOD and became evil necessitating the postponement of the judgement so they would not be condemned with the tares, until they could be redeemed and sanctified, brought back to their first faith.
Thus the sinfulness of the elect is totally different from that of the reprobate non-elect with a huge difference in consequence, HUGE! If someone can be saved they will be saved. If they can be forgiven they will be forgiven. No one will be in hell who could be forgiven. And so far I take Augustine as a NO authority on any Christian matter. Since I believe we were elected and became sinners prior to our conception on earth, I do accept Calvin's pov that time on earth is meaningless about our fate but only whether we are elect or not...both elect and non-elect foetus die in the womb and before baptism.
