Oh, I disagree with the OP.
I do wonder if there is too much emphasis on it.
There isn’t enough emphasis on it. The world no longer believes anything is sin, no longer believes in sin, period.
Pope Francis was recently quoted by the Vatican Insider as saying “When you lose the sense of sin, you lose the sense of the Kingdom of God" When the Lord is absent among men, they “lose the sense of sin” and others risk falling victim to “Christian mediocrity.” Francis warned against this in this morning’s homily in St. Martha’s House.

In “Reconciliation and Penance” Pope St. John Paul II wrote an entire section on the topic of the loss of the sense of sin. I quote in parts:
I asked two years ago in an address to the faithful “Is it not true that modern man is threatened by an eclipse of conscience? By a deformation of conscience? By a numbness or ‘deadening’ of conscience,” Too many signs indicate that such an eclipse exists in our time.
When the conscience is weakened the sense of God is also obscured, and as a result, with the loss of this decisive inner point of reference, the sense of sin is lost. This explains why my predecessor Pius XI, one day declared, in words that have almost become proverbial, that “
the sin of the century is the loss of the sense of sin”(emphasis mine).
It is not fair to ever expect anyone, including yourself, to be perfect.
It may not be fair but perfection is what we are called to. Jesus said (in Matthew 5:48) “You, therefore, must be perfect, as your heavenly Father is perfect.” James echoes this in his epistle (1:4) “…that you may be perfect and complete, lacking in nothing.” James’ whole chapter is about being perfect in the virtues.
St. Teresa of Avila wrote “It is evident that one who would merely aim at avoiding mortals sin would not be living according to the standard of moral conduct outlined in the Gospel. Our Lord proposes to us as the ideal of holiness the very perfection of Our Heavenly Father: “Be ye therefore perfect, as also your heavenly Father is perfect.” Hence, all having God for their Father must approach this divine perfection - which evidently cannot be accomplished without progress.”
We are called to be Christians, not Christ.
Are we not members of the Body of Christ? Here on earth? What else does it mean to be Christian but to be as Christ-like as possible? If we are what we eat, at least as Catholics we are to be Christ or we make a mockery of the true Presence of Our Lord. Every time we partake of the Body and Blood we should be striving to allow God to transform us more and more into Christ’s presence here on earth.
I honestly do not believe with our own free-will and constant prayer a person can fully stop sinning.
I don’t believe this, either. It is by God’s GRACE that we can be freed from sin. By his grace we become aware of the sin in our lives, rout it out, confess it, and conquer it. St. Teresa goes even further and advises that we not only confess our mortal and venial sins but also bring our temptations, imperfections, and dislikes to our confessors for advice and counsel in overcoming them.
Forgiveness and Mercy are for those who are repentant, they are the ones who are willing to receive these gifts from God. Unfortunately without a rightly formed conscience and without a sense of sin there is no repentance.
