Which motive is NOT included among the common motives for arson?

The motive of self-defense is not commonly associated with arson. In the context of arson, motives typically involve intentional actions that aim to harm or intimidate, cover up other criminal activities, or express ideological beliefs.

Revenge can be a driving factor behind arson, where individuals set fires to retaliate against someone or something that has wronged them. Similarly, crime concealment refers to the act of destroying evidence or covering up a crime, which is often accomplished through fire. Extremism, another recognized motive, involves using arson to further particular ideological, political, or religious agendas.

In contrast, self-defense typically refers to protecting oneself from immediate threat or harm and does not align with the intentional and destructive nature of arson. Setting a fire is an act that usually creates risk and potential harm to others, which does not fit within the rationale of self-defense. Thus, self-defense is not a common motive for arson.
