What is meant by "mala in se" crimes?

"Mala in se" refers to crimes that are considered inherently wrong or evil by their very nature, independent of laws or statutes. These offenses are universally recognized as morally reprehensible, such as murder, rape, and robbery. The intrinsic nature of these crimes evokes a strong emotional and ethical response from society, highlighting a moral consensus that transcends legal definitions.

In contrast, "mala prohibita" refers to acts that are wrong only because they are prohibited by law, not because they are inherently evil. Examples of mala prohibita crimes would include traffic violations or the use of certain drugs, which society may not view as immoral in the same way that mala in se crimes are viewed.

This distinction is important in criminology as it helps to understand the moral underpinnings of laws and the varying societal reactions to different types of crimes. Understanding this concept offers insight into how societal norms and values shape our legal systems and the perceptions of criminal behavior.
