What Makes a Person Who They Are?

I think that it's more to do with the kind of universal interests that people have in violence and cruelty. I mean we all wonder where the deep down we might be capable of that. You say you're interested in what makes a person who they are but I have to put it to you that perhaps there's a bit of a morbid fascination? Yes I don't see it as a fascination. The very fact that we have a huge interest in true crime in terms of television and books and programs and podcasts is just part of it.
