I have noticed in my game running I very rarely have any clearcut easy to peg evil people. Everyone exist in a spectrum of experience experience and traits that lead to who they become. When I run a game I let that view of people effect how i tend to run npc's. Now matter how despicable they have reasons for the things they do and rarely is it for evil's sake.
here is an example of a single meal can take up a lot of calories. Not going to happen often but I got to have dinner with friends at ruby tuesdays. All in all not how I want to spend my calorie allotment for a day on a regular basis but every once in a while is pretty nice.
