They should come labeled

According to Medichat.com, these are the symptoms of a psychopath. I don't know that it's the most reliable site out there (and I have been helpless to resist correcting some of the more egregious typos), but it has inspired me to think ... how many people are like Casey Anthony, but just haven't been provoked to overt criminality yet? I'm not kidding. My least-favorite ex has 16 of these characteristics, and after encountering him, my life has never been the same.

Since people like this initially appear so normal, even attractive, the least Mother Nature could do is give us a fighting chance by marking them somehow.
