NOTE: I said they would rather do it, not that they would do that. Most people do not commit crime because of a combination of morals, respect for others, and fear of punishment. So even in a society where there is no punishment for breaking laws, you are correct the majority of people would not break them becasue of respect and compassion and morals. However, the criminlas in our world would definitely commit crime in your system devoid of punishment, and a new group of people who are immoral but only fear the punishment would now become criminals as well.
