Confessions of A Freelancer

I'm writing about a slightly amoral but charming guy---you'll read the piece soon, I promise--and wanted to describe his actions as immoral and negating all that is good in the world. I tried "uncalculatingly Jarrysian" after Alfred Jarry but that got spell-checked to Parisian. Then I thought, and this is embarrassing, "uncalculatingly Hobbesian" sounds good. Sadly, I have no idea what Hobbesian means, other than it has to do with Thomas Hobbes. But I'll use it anyway. Function follows form! Fake it til you make it. Etc.
