Is arson mala in se or mala prohibita crime?

Arson is considered a mala in se crime because it inherently involves wrongful conduct that poses a significant threat to life and property. The act of intentionally setting fire to buildings or land is inherently harmful and reflects a moral turpitude that society condemns. While laws governing arson may vary by jurisdiction, the act itself is universally recognized as fundamentally wrong, distinct from mala prohibita crimes, which are wrong only because they are prohibited by law.
