People often seek out what is bad for them due to a variety of reasons. For example, some may have low self-esteem and seek out negative reinforcement, while others may be naturally prone to risk-taking behavior. Additionally, people may seek out what is bad for them in an attempt to fill a void in their lives. This may be due to feeling unhappy or unfulfilled and wanting to alter their current state in any way possible. In some cases, people may do so out of curiosity, not fully understanding the consequences of their actions.
