Blameworthy; culpable; having committed a TORT or crime; devoid of innocence.
An individual is guilty if he or she is responsible for a delinquency or a criminal or civil offense. When an accused is willing to accept legal responsibility for a criminal act, he or she pleads guilty. Similarly, a jury returns a verdict of guilty upon finding that a defendant has committed a crime. In the event that a jury is not convinced that a defendant has committed a crime, jurors can return a verdict of not guilty, which does not mean that the individual is innocent or that the jurors are so convinced, but rather that they do not believe sufficient evidence has been presented to prove that the defendant is guilty.
In civil lawsuits, the term guilty does not imply criminal responsibility but refers to mis-conduct.
