The Yoda card cuts both ways, though. Luke lights up first in the cave on Dagobah, and his aggressiveness there seems to be the reason that he failed the test.

Yoda said:

Your weapons; you will not need them.

You're right on the money.

This is the big contradiction in the OT that nobody likes to talk about.

On the one hand, it seems like Yoda doesn't want Luke to use violence to overcome the Emperor and Vader.

You can make the case that Yoda and Kenobi are just trying to keep Luke from falling to the dark side through a dependence on anger, fear and aggression, but I always thought Lucas missed a golden opportunity here.

I had an idea several years ago that played out for a long time on a couple of old Star Wars message boards where I theorized that Yoda and Kenobi were using reverse psychology to get Luke to try and reach his father through feelings of regret rather than violence.

It was based on an idea that Yoda and Kenobi knew that Anakin wasn't beyond redemption, but they simply couldn't tell that to Luke. It was something he had to learn (feel) on his own.

But it's kind of a long story that I'd rather not get into anymore.

Too many years discussing it.
