Which word describes someone unrestrained by convention or morality?

The word "profligate" accurately describes someone who is unrestrained by convention or morality, as it originates from a Latin term that implies a recklessness or wastefulness, particularly in terms of moral integrity or social norms. A profligate person often engages in behavior that is considered extravagant or immoral, living without regard for the moral or ethical standards typically upheld by society. This term captures a deeper sense of moral disregard than simply being wild or reckless, which may pertain to behavior without necessarily involving the same level of ethical transgression.

In contrast, "reckless" suggests a lack of caution or care, but it does not inherently convey a disregard for moral or societal norms. "Wild" refers to untamed behavior, but it lacks the specific connotation of moral or ethical failure that profligate carries. "Extravagant" primarily focuses on excessive spending or lavishness without the explicit moral deficiency associated with profligacy. Therefore, profligate is the most precise choice for describing someone who lives without restraint from conventional or moral considerations.
