willful

This term carries a strong sense of agency and stubbornness. When applied to legal or formal contexts, it suggests a conscious decision to ignore a known obligation, making it more severe than a simple mistake or negligence. It implies a level of defiance that transforms an error into a transgression. In a personal or behavioral context, the word evokes an image of rigidity. It describes a personality trait where the individual is locked into their own desires, often bordering on arrogance or childishness. It differs from being determined or persistent because it suggests a disregard for reason or authority.
