That is below the dignity of a human being for every single human being is created in the image and likeness of God and therefore has a dignity far beyond what one can imagine. Because of the sin of Adam and Eve, a human being has a weakened human nature and has a propensity to do wrong. One must accept this fact but should understand that in no way does this take away from their dignity. When one confesses their wrong doings, one should do so with dignity and with humility, humility being basically truth. Christ's response will always be and can only be one of welcome and forgiveness.
Confession is more, much more than just forgiveness.
It is also a healing, something most seem to be unaware of. Once absolved from their sins, one with faith can feel a real sense of relief and a joy that once again things are right with themselves and God. This sense of well being gives one courage to go on, to make greater effort in striving to overcome faults. And in reality, most people confess faults much more than actual transgressions or sins. Because to commit a real sin, minor or major, one must know that something is wrong and then deliberately determine to do it anyway.
