Which character trait signifies absence of fear toward a threat?

Courage is the character trait that signifies an absence of fear in the face of a threat. It embodies the ability to confront danger, pain, or challenges despite feeling fear. Courage does not imply the absence of fear in a literal sense; instead, it reflects the willingness to act in spite of that fear.

While confidence relates to a belief in one's own abilities, which can reduce feelings of fear, it does not inherently denote the active response to a threat. Hardness often connotes a lack of emotional sensitivity or flexibility, not necessarily an absence of fear but rather a tough exterior. True aggression indicates a hostile or violent approach towards a threat, but it may stem from fear or other motivations rather than a courageous response. Therefore, courage is the most accurate descriptor of facing threats without fear.
