Surface Forms

Morphology

guilty + as + sin

The overall meaning is partly derivable: a learner who knows 'guilty' and 'sin' can infer a strong degree of wrongdoing, so they will likely guess it means very guilty. However, 'as sin' functions as a colloquial idiomatic intensifier rather than a strictly compositional comparison, so the exact pragmatic force and register are not fully predictable without exposure.

Etymology

Guilty as sin uses the strong image of sin as the worst kind of wrong. If someone is guilty 'as sin' they look clearly and deeply ashamed, so the phrase means 'feeling or appearing extremely guilty'.
