I consider Yoda to be just about the most evil character that I’ve ever seen in the history of literature. I have gotten people into tongue-tied snits unable to name for me one scene in which Yoda is ever helpful to anybody, or says anything that’s genuinely wise. 'Do or do not, there is no try.' Up yours, you horrible little oven mitt! 'Try' is how human beings get better. That’s how people learn, they try some of their muscles, or their Force mechanism heads in the right direction, that part gets reinforced and rewarded with positive feedback, which you never give. And parts of it get repressed by saying, 'No, that you will not do!' It is abhorrent, junior high school Zen. It’s cartoon crap.
