Someone who uses violence for political reasons?

A person who uses violence for political reasons is often referred to as a political terrorist or insurgent. Such individuals may believe that violent actions are necessary to achieve their ideological goals, challenge authority, or instigate change within society. Their actions can include bombings, assassinations, or armed attacks, often aimed at instilling fear or coercing governments and populations. This form of violence is typically justified by the perpetrators as a means to an end, regardless of the moral and ethical implications.
