Serial killers are dangerous people. But some people love danger. The love of dangerous situations is fueled by hormones. One of the hormones, dopamine, is released when someone is stressed. It creates a feeling of pleasure in the brain. Dopamine is released when riding a roller coaster, which is why some people like riding roller coasters. When someone dates a toxic romantic interest, dopamine is also released. The people who enjoy the dopamine high want more toxic relationships.
Danger isn't something to want to be around. Lions are dangerous, so people stay away from them. Storms are dangerous, so people evacuate their homes. Serial killers are also dangerous and should be arrested. Although dopamine makes someone feel good in dangerous situations, wisdom should be used so they don’t get hurt.
[P1] Dopamine makes danger desirable. [P2] Serial killers are dangerous.
