When discussing this topic, we need to deal with it carefully, because religion and belief are an extremely important part of many people's lives and involve deep emotions and values. However, there are some historical cases that show that certain religious leaders or groups may use human fear to manipulate believers, especially in doomsday situations. The following is a fictional description based on historical events and psychological theories, designed to reveal the potential mechanism of this phenomenon. --- In a fictional religious group, the leader is called “Prophet Elias.” He claimed to be the messenger of God, shouldering the task of conveying to the world the prophecy of the coming end of the world. Elias used the doomsday prophecies in the Bible, combined with natural disasters, political turmoil and technological threats in the real world, to carefully weave a convincing doomsday scene. Elias' sermon was full of detailed descriptions of the end of the world: the earth will crack, the sky will burn with flames, and mankind will face an unprecedented disaster. He claimed that only those who fully obey him and are willing to give up their worldly desires can obtain God's blessing in this catastrophe and enter the eternal kingdom of heaven. In order to deepen the fear of believers, Elias regularly organizes gatherings to broadcast doomsday-themed video materials to show the tragedies of natural disasters and the horrors of war. He also uses social media and online platforms to spread “evidence” about the approaching end of the world, such as UFO sightings and extreme data on climate change. This information spread rapidly among believers, further deepening their fear and uneasiness. In this atmosphere, Elias began to ask believers to make extreme sacrifices. He declared that only those who are willing to give up their property, family, and even their lives can prove their loyalty to God and thus be redeemed. He encourages believers to participate in dangerous rituals, such as hunger strikes, self-mutilation, and even collective suicide, in order to “purify the soul” and “welcome the coming of the kingdom of heaven.” Elias also established a strict hierarchical system to ensure the absolute obedience of believers to him. He appointed loyal followers as “guardians”, responsible for monitoring the behavior of other believers and punishing anyone who questioned or violated his orders. In this way, Elias successfully transformed the fear of believers into absolute loyalty to him, making them willing to do any extreme behavior for him. In the end, Elias' manipulation reached its peak. In a grand rally, he announced that the end of the world was coming, and called on believers to commit suicide collectively to “ascend to the kingdom of heaven.” Driven by fear and blind faith, many believers executed his orders without hesitation, causing a terrible tragedy. --- This fictional story reveals how certain religious leaders use human fear, especially doomsday theory, to manipulate the behavior of believers. By creating fear, controlling information, and establishing a strict hierarchy, these leaders can make believers willing to make extreme sacrifices and even give up their lives in order to obtain the so-called “blessing of God.” This phenomenon reminds us of the importance of maintaining rational and critical thinking in the face of extreme speech and behavior, and at the same time, social and legal mechanisms are needed to protect people from such manipulation.
