Am I the Mastermind Behind This?

Before my sister died, she said that the light in her heart was eaten away by something. The police thought it was suicide, until I found out that her mentor collapsed at the memorial service and her best friend went crazy in the police station. An unexplainable and extreme emotion is spreading like a plague among relatives and friends. As a former psychological profiler, I risk everything to get to the bottom of it. I found that all the victims had been exposed to a strange "emotional carrier" on the Internet. It can accurately induce depression or mania, turning people into walking zombies or socially dead lunatics. And this is actually a precise cleanup that is beautified as "social emotional optimization." The "Pure Land" company that controls everything regards me as a virus and mobilizes the entire population to hunt me digitally. My identity was stigmatized, my past was exposed, and I became the city's most dangerous public enemy. Until the defected genius scientist told me the cruelest truth: "Chen Mo, you are not a hunter." "You are the last infected person we release." My sanity was counting down, and they wanted me to kill myself on air like crazy. Now, I hold the "cleanse" button pointed at hundreds of millions of people. Should I destroy it, or... Return all the truth and evidence to this sleeping world as a more deadly plague?
