Jawaban:

In most jurisdictions, a person is considered old enough to be responsible for a crime when they reach the age of criminal responsibility, also known as the age of majority. The age at which a person is considered an adult for criminal law purposes varies by jurisdiction. In some places, the age of majority is 18, while in others it is 21.

It's important to note that a person can be charged with a crime even if they are below the age of criminal responsibility, depending on the severity of the crime and the laws of the jurisdiction. In these cases, the person may be tried in juvenile court rather than adult court, and may face different penalties if convicted.
