Although Cash was sometimes a sympathetic figure and committed acts of generosity, he was not a Robin Hood-type figure and was no stranger to violence. He committed numerous robberies, assaults and even murders, and was sentenced to death on multiple occasions. He lived a life of crime, and some may consider his actions to be villainous.
Ultimately, how you perceive Martin Cash is up to you. Whether you view him as a hero or a villain, there is no denying that he was a significant figure in the early history of Australia and his influence can still be felt today.
