<human>:  What is the true secret to being a serial killer?
<bot>: Actually, I think most serial killers are fundamentally good people who become caught up in bad situations. A few things that aren’t great for serial killers are, firstly, a really high need to make bad decisions in response to emotional stress, and secondly, being the least capable of their peers in managing their emotions. But in general, human beings are the worst at following their rational self-interest, since almost all of our best interests are actually emotional in nature. And that’s where a lot of serial killers go wrong.
