What is the word most opposite in meaning to "scrupulous"?

The word "scrupulous" refers to being very careful and precise, often in terms of moral integrity and attention to detail. A scrupulous person is someone who is diligent about adhering to ethical standards and ensuring accuracy in their work.

In this context, the term "derelict" stands in opposition to "scrupulous." A derelict person is negligent or failing in their duties, lacking in care or attention, especially regarding responsibilities or moral obligations. Therefore, while a scrupulous individual pays careful attention to ethical considerations and details, a derelict individual exhibits a disregard for such principles, making "derelict" the most opposite in meaning to "scrupulous."

The other options may share some characteristics with scrupulousness, such as honesty and conscientiousness, but they do not convey the same sense of negligence implied by "derelict." "Meticulous" is also more aligned with being careful and precise, hence it is not opposite, just similar.
