Final answer:
Mala in se crimes are inherently evil or wrong, while mala prohibita crimes are prohibited by law but may not be inherently wrong. The division of penalties can vary, but mala in se crimes generally have more severe penalties.
Step-by-step explanation:
Mala in se refers to acts that are inherently evil or wrong, such as murder or theft, and are universally condemned. Mala prohibita, on the other hand, refers to acts that are prohibited by law but may not be inherently evil or wrong, such as traffic violations or gambling. The division of penalties between these two categories can vary depending on the jurisdiction, but generally, penalties for mala in se crimes are more severe than those for mala prohibita crimes.
