Leonardo’s statement argues that failing to respond to wrongdoing can have the practical effect of encouraging it. If harmful conduct produces no consequences, those responsible may conclude that it is tolerated, while others may see little reason to avoid similar behaviour.

The remark links justice with responsibility for enforcement. Punishment here can be understood broadly as an appropriate consequence or corrective response, rather than necessarily severe retribution. The central idea is that rules and moral standards lose force when violations are consistently ignored. Inaction can therefore contribute indirectly to the continuation of harmful conduct.

The quote can be applied to law, institutions and everyday situations involving accountability. It highlights the importance of proportionate responses to misconduct while also implying that those with authority bear responsibility for how they react. Its broader claim is that tolerating serious wrongdoing can help create conditions in which it persists.
