Doomsday cults are groups that believe in an impending apocalypse or catastrophic event that will lead to the end of the world. Members often follow a charismatic leader who interprets religious texts or prophecies, claiming to have special knowledge about the coming disaster. These beliefs can lead to extreme behaviors, including isolation from society and preparation for survival. Many doomsday cults have gained attention due to their dramatic predictions and sometimes tragic outcomes. Notable examples include the Heaven's Gate group and the Branch Davidians, both of which ended in violence and loss of life. Such cults often exploit fear and uncertainty to attract and retain followers.
