Many people who choose to live outside square-lawed society rely on people remaining docile and sticking to principle in order to prey on them, or at least to live a lifestyle where they don't have to collaborate with larger society to reap its rewards. It took me years to un-program "assume good intent and empathy" with people I didn't know that were trying to take advantage of me.
I simply can't stand thieves. I wish that we had really great public services and transportation--not only would this reduce a huge amount of current theft, it would make actual theft obviously inexcusable.
