Mainly, I just wish I'd never encountered the website Serial Killers Ink, which showcases terrible artworks by the perpetrators of some truly terrible crimes. I don't like to think about the kind of person who'd pay, say, $175 for a portrait of Jennifer Love Hewitt by Elmer Wayne Henley, who is serving six life sentences for mass murders in Houston in the 70s, or $60 for a cartoon panda by a man with the soubriquet of "the internet's first serial killer". It's all very depressing. But I can't deny it: I kept clicking. The flicker of fascination was there.
