… If you would like to develop an informed perspective on the historical development of the Catholic doctrine of the Atonement, let me suggest an english-language text from the 1800s which is freely available on

While written ~150 years ago, the information is all still relevant …
To give you an idea of why the “History” book that I’ve suggested to you is a perfect fit given your concerns (and those of many others who have posted similar questions/statements in this forum over the years), let me quote from Chapter 1:
PRELIMINARY CONSIDERATIONS ON THE SUBJECT, AND THE METHOD OF TREATING IT.
THAT Jesus died, the Just for the unjust, to redeem mankind from the bondage of corruption, and restore the broken communion between earth and heaven, is, and ever has been, a fundamental verity of the Christian faith. From that uplifted cross, for eighteen centuries, He has been drawing all men by the ‘cords of Adam’ to Himself. Round the altars where that one true Sacrifice, offered once in blood on Calvary, is presented perpetually in a bloodless mystery, from the rising to the setting of the sun, has been gathered through those eighteen centuries of her chequered history the faith, the penitence, the devotion of the Church He purchased by that greatest pledge of love.
Yet, even as then among the spectators of the crucifixion there were some who worshipped and some who doubted, and its stillness was broken by the questionings, or the jests, or the mockeries of those for whose sake it was endured, so it has been till now. And doubts have multiplied tenfold since the first controversies of the Reformation period involved the whole subject in the confusions of a theological warfare, where men darken counsel with many words, and strive rather for a party triumph than for simple truth. Forgetting or greatly underrating, for the most part, the significance of the Incarnation as the centre-point of all Christian belief, the first leaders of the movement in the sixteenth century dragged forward into disproportionate prominence, and often in connection with an erroneous theory of ‘imputation,’ one side and one only of that Divine mystery, namely, the doctrine of the Atonement. And hence there has grown up in many quarters a way of looking at the doctrine, and speaking of it, full of difficulties to the devout believer, and offering abundant opportunities for the cavils of the sceptie. In our own country this has been partly due to the theological influence of Paradise Lost, which had become for a large number of Englishmen a kind of supplementary Bible. The Arian opinions of Milton on our Lord’s Person, have strengthened the hold obtained over the national mind by what is in fact an Arianizing conception of His work.
(1) It has been so represented as to cloud our most primary conceptions of the attributes of God; and to imply, or seem to imply, a division of will between the Persons of the undivided Trinity, in whom being and will are one. And so men have come to complain that they cannot believe in a justice which strikes the innocent, while it spares the criminal; that they cannot understand a love which waits to forgive till it has exacted rigorous compensation; or recognise the holiness of that displeasure against sin which is content to exhale in displeasure against the Sinless One. Such objections may often be urged in a tone of mockery, or disbelief; but it is not always so. It will not then, I trust, be an unprofitable task to show that the doctrine of atonement held and taught from the beginning in the Catholic Church is open to no such criticism. An investigation of her teaching, as laid down by the Fathers and later theologians who are the accredited interpreters of her mind, will prove that the opinions fairly open to objection are no part of it, but are either those of particular writers or schools only; or such as have prevailed for a season and then passed away, like the notion of a ransom paid to the Evil One; or were put forward from the first with an heretical animus, and have never found a home within her pale; or are the doctrines of those who have formally renounced her creed. Meanwhile, it will not be out of place to premise some explanations, at starting, in reference to certain leading misconceptions on the subject.
First, then, let me repeat discrinctly what has already been implied, that no division of mind or will is even conceivable between the First and Second Person of the holy and undivided Trinity.
The Atonement was not, if one may put such blasphemy into articulate words, a device of the Son to avert the wrath or appease the justice of His offended Father, as when He is said in a well-known hymn to have “smoothed the angry Father’s face.” Sin is equally displeasing to the Father and the Son, and to the Father as much as to the Son belongs the love which by the mystery of redemption “devised a way to bring His banished home.” The Father sent the Son in likeness of sinful flesh, and by the Eternal Spirit was He conceived in Mary’s womb, and offered on the Cross. The atonement is the work of the whole Trinity, and the sacrifice of the Cross, like the sacrifice of the Altar, is offered to the whole Trinity. To conceive of the Father being angry with His sinless Son, and inflicting on Him the punishment He would else have inflicted on us, is to forget that " the Father is God, the Son is God, and the Holy Ghost is God, and yet They are not Three Gods but One God." The justice which required satisfaction and the mercy which provided it, are the justice and the mercy of the Triune God. In the language of St. Leo, which will be quoted again further on, “One is the kindness of Their mercy as the sentence of Their justice, nor is there any division in action where there is no diversity of will.” It is only necessary to insist upon this, because it is so frequently forgotten . . .
(1) See Preface to Benson’s Sermons on Redemption, from which I quote the following apposite passage : — " The act of redemption is not the mere act of the love of the redeeming Person, but the manifestation of the love of the Triune God. God the Son came upon earth to satisfy His own justice, as much as to satisfy His Father’s, and for the accomplishment of His Father’s love to man, as much as for His own. If this truth is often lost sight of, it is because the consubstantial Godhead of the father and the Redesmer is ignored."
