unprovoked
Lacking any instigation
Unprovoked describes an action, especially an aggressive one, that occurs without any preceding cause or justification.
An unprovoked attack comes without warning or reason—the victim did nothing to invite it.
The word appears most often in contexts of violence or hostility: an unprovoked assault, unprovoked aggression.
It carries strong moral weight, suggesting the aggressor bears full responsibility since there was no provocation to which they were responding.
