Why did you quote this verse about "destruction" when you believe in"universal reconciliation?"
2 Thess.1:9 is not a difficult text to reconcile with the Scriptural teaching of universal reconciliation(UR). Simply put it speaks of an indefinite duration (=aionias,
often deceptively rendered eternal/everlasting) of destruction.
Therefore, whatever you understand by the word "destruction" - whether death, annihilation or ruin - the text is perfectly harmonious with UR passages of the Bible.
Problem solved. Now you can rejoice in the Good News!
2Thess.1:9 Who, indeed, a penalty, shall pay—age-abiding destruction from the face of the Lord and from the glory of his might— (Rotherham)
9 who shall incur the justice of eonian extermination from the face of the Lord, and from the glory of His strength" (CLNT)
who shall suffer justice -- destruction age-during -- from the face of the Lord, and from the glory of his strength, (2 Thess 1:9, YLT)
A recent new translation by EO scholar David Bentley Hart reads: "Who shall pay the just reparation of ruin in the Age, coming from the face of the Lord and the glory of his might" (A Translation: The New Testament, 2017, Yale University Press).
A Greek lexicon at the following url states re the Greek word olethron ("destruction") at 2 Thess.1:9:
"...Hierocles 14, 451b has the thought that the soul of the sinner in Hades is purified by the tortures of hell, and is saved thereby..."

Compare that above statement to:
"In Ancient Greek mythology, Olethros was the personification of Havoc and probably one of the Makhai. Olethros translates roughly in ancient Greek to "destruction", but often with a positive connotation, as in the destruction required for and preceding renewal."
Here we see "destruction" is for the good of the person:
... deliver such a one to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord Jesus. (1Cor 5:5). He who is finding his soul will be destroying it, and he who destroys his soul on My account will be finding it. (Mt.10:39)
Here we see destruction was temporary:
Jesus answered them, "Destroy this temple, and I will raise it again in three days." (Jn.2:19)
Lamentations 3:22 and 3:31-33, The steadfast love of the Lord NEVER ceases, his mercies NEVER come to an end. . . .
Lam.3:31 For the Lord will NOT cast off FOR EVER:
32 For if He causes grief, Then He will have compassion According to His abundant lovingkindness. 33 For He does not afflict willingly Or grieve the SONS OF MEN.…
Rom 5:18 Consequently, then, as it was through one offense for ALL MANKIND for condemnation, thus also it is through one just act for ALL MANKIND for life's justifying."
Rom 5:19 For even as, through the disobedience of the one man, THE MANY were constituted sinners, thus also, through the obedience of the One, THE MANY shall be constituted just."
Paul makes a parallel between "the many" who were condemned & sinners and those who will be justified & constituted just.
“In Romans 5, the justification is co-extensive with the condemnation. Since all share in one, all share in the other. If only a certain portion of the human race had partaken of the sin of Adam, only a certain portion would partake of the justification of Christ. But St. Paul affirms all to have been involved in one, and all to be included in the other.”
Therefore there is salvation after death. And corrective punishment.
Jesus shall see of the travail of His soul & be satisfied. Not satisfied a little bit, but the vast majority fried alive forever.
"He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities." (Isa.53:11).
For how "many" (not few) did He "bear their iniquities"? All.
1 Cor.15:22 AS in Adam ALL die SO ALSO in Christ shall ALL be made alive.
1 Cor.15:28 And when ALL shall be subdued unto him, then shall the Son also himself be subject unto him that put ALL under him, that God may be all in ALL.
Col.1:16 For by Him ***ALL*** was created that are in HEAVEN and that are on EARTH, visible and invisible, whether thrones or dominions or principalities or powers. All was created through Him and for Him.
20 and by Him to reconcile ***ALL*** to Himself, by Him, whether on EARTH or in HEAVEN, having made peace through the blood of His cross.
Fortunately no "eternal death" ever appears in the Sacred Scriptures (66 books of the Bible). To the contrary, death will be abolished (1 Cor.15:26).
"Just as surely as the abolition of slavery entails freedom for those formerly enslaved, the abolition of death entails life for those formerly dead."
1 Cor.3:12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; 13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. 14 If any man's work abide which he hath built thereupon, he shall receive a reward. 15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
