Why didn't Yoda teach Luke how to block force lightning?

[TREK_GOD_1]

When it comes to Yoda's training of Luke in TESB, the concept of lightning from fingertips didn't exist yet.

Kor

Yes--not on screen, but the ROTJ novel was pointed out as it suggests Luke concluded that the lightning was force-generated, so it could be blocked with the force. That--at least--says Luke was rather smart and/or was taught that the force can block anything from another force user, without it being spelled out in the script to TESB or ROTJ.

But the Jedi have never before considered lightsabers representative or indicative of the dark side and throughout the films, until that moment, using a weapon for defense was considered very different from for aggression.

tossing his lightsaber aside as a show of his complete rejection of said dark at the most important moment of the SW films.

That meant tossing the lightsaber was Luke rejecting its use to fulfill a dark side act that would have sealed his fate, not that the weapon was indicative of being a practitioner of the dark side in general.

Simply another fool. There was a warning sign on the door to the emperor's chambers reading ‘WEAR RUBBER BOOTS BEFORE ENTERING’, but that presumptuous binky-sucking Jedi ignored it. Nobody follows safety instructions any more. We work our assess off under severe stress down here in maintenance, try to secure every inch of the goddamn Death Star – you know big that thing is? We install signs all days – wet floor, don't stare directly into the beam, don't touch the power lines with both hands, don't cross before protracting the bridge, don't eat the kyber crystals... And all the uppity idiots will simply ignore them.

Just the other week we were visited by a Grand Moff who spend a day in the infirmary because of intestinal silicosis after consuming a handful of ground kyber crystals, and a couple of years ago my aunt Mon Tico died after some uppity idiot carried a torpedo in the reactor room and blew the whole station. And now Baby and Dad Vader got electrocuted. Give me a break.

I'm gonna tell my children to work in bombers, cause even those are safer. Plus, the VIPs never make it aboard one of those, so you'd steer clear of their recklessness throughout your career.
