For criminal liability to exist based on an offender's act, what must be proven?

For criminal liability to exist based on an offender's act, it is essential to prove a direct relationship between the act and the harm caused. This means that there must be a clear causal link between what the individual did and the resulting negative consequences, such as injury to a person or damage to property. Establishing this connection is crucial, as it reflects the principle that an individual should only be held legally responsible for actions that have a demonstrable impact on others.

To illustrate this, consider a scenario where an individual fires a gun into a crowd, resulting in injury to a bystander. Here, the act of firing the gun directly correlates with the harm experienced by the bystander, satisfying the requirement for establishing criminal liability.

In contrast, simply having a financial motive or a history of similar offenses does not necessarily contribute to proving that the act caused harm. Likewise, while intent to commit a crime is a significant aspect of many criminal charges, the actual relationship between the act and the harm remains foundational for establishing liability in a legal context.
