Which of the following best describes wanton murder?

Wanton murder is characterized primarily by reckless behavior that shows a disregard for life, leading to the death of another person. This definition aligns with the criteria for second-degree murder in some jurisdictions, where intent to kill is not necessary but a person may still engage in behavior that is so reckless or indifferent to the value of human life that it results in someone's death. This fits well with the concept of wantonness, which implies a deliberate disregard for the consequences of one's actions.

In this context, the notion of reckless behavior is central, as it involves an awareness of the potential for harm but a willful choice to act anyway, reflecting a severe lack of concern for the risk posed to others. Thus, the characterization of murder caused by reckless behavior accurately encapsulates what wanton murder entails.
