Does the vanishing of the hatred for a sin from the heart and the lack of hope in getting rid of it lead to disbelief (kufr)? And is there a consensus on this?

A sinner may dislike the sin because he believes that religion has forbidden it, and he loves his religion. If he does not dislike it, he is deficient in faith, not an unbeliever or hypocrite, provided that he generally loves his religion. A believer loves good deeds and dislikes evil deeds, and he dislikes disbelief, immorality, and disobedience. Whoever does not dislike these three is not a complete believer, but he may possess the root of faith. As for one who does not detest anything from Allah's forbidden acts of disbelief, immorality, and disobedience, he is a disbeliever. And whoever is pleased with a sin and is content with it is like its perpetrator. Lack of hope in getting rid of a sin does not lead to disbelief; rather, it is from the whispers of Satan that may lead to despair of Allah's mercy, which is more dangerous than committing the sin itself.
