wicked / immoral / decadent / indulgent
Adjective
comp: more sinfulsup: most sinful
This term carries a heavy moral weight when used in religious or ethical contexts, implying a transgression against divine law or a deep personal failing. It suggests a state of guilt or a need for redemption, often evoking a sense of shame or spiritual corruption. In modern, secular usage, the word has shifted toward a playful or ironic connotation. When describing food or luxury, it suggests a decadent pleasure that is "wrong" only because it is too indulgent to be healthy or modest, stripping the word of its original gravity.
