Arson is a serious crime that was punishable by death under the common law. Presently, it is classified as a felony under most statutes, punishable by either imprisonment or death. Many jurisdictions impose prison sentences commensurate with the seriousness of the criminal intent of the accused. A finding, therefore, that the offense was committed intentionally will result in a longer prison sentence than a finding that it was done recklessly. When a human life is endangered, the penalty is most severe.
