How come none surival Jedi unable finish Vader off

[Jason 27]

I see as Vader suit major weakness. Simple use the force to mask for all for could be fetal to Vader. How come Jedi used force such way kill him. Worst yet force lighting also damage his suit and would be fetal.

 

One might argue force lighting something dark side of the force no Jedi dream of using

This fail to take account two problem first we see them use force chock. Luke used force chock. Even we going take account he may little less careful when came to using force weapon Jedi were before him. Seen both Yoda and Obi using the force push as weapon against living things. In pratice any surival Jedi all include Yoda and Obi with Vader weakness should gonner.

 

I can think few possible answers about 4

 

Vader might will able block force lighting been very will train that point block Empire force lighting. In special Environments he could train by Emperor himself to point it real problem force lighting going with either lightsabre. Jedi even try do work for that reason as remove helmet survival for minutes enough time to get back on. Or train such way that his used force effective prevent happen first place. No mean he could survival light-saber dual with Emperor.

 

Problem with this one first even surprise attack force lighting dangers.  Jedi choice use straight out fight.  Worst yet his face two Jedi he could not block Light saber form both both sides,  Darth Vader is pretty screw.  Even if he can resistance the pain his suit going give going light saber attack. Means able just retreat if Return Jedi say anything he have few minutes at most to defeat the two of them or one Jedi knight before  either dying environment which could live.

 

Second possible   he normal not send after Jedi first place. This back more Star War Rebels.  First Star War Rebels they dark agencies unable to defeat even partly train Jedi. Full train Jedi wash the floor with dark force wielders. Even possible try gain up them in general. Even not per say explain Vader survival all together.  

 

Another possible Emperor more involved in fighting the Jedi knights. Vader role was more limited. In thoery role more hunting down Emperor down most of the killing. Problem with this theory goes against all know cannon. Vader fort-lines all major battles we see Star War with Rebels.

Star War Rebels to all the three movies that show Star War Emperor.

 

Maybe Jedi were powerful enough take Vader without problem and the Emperor want live let live policy. Even Jedi were powerful how big threat real be to the Emperor along stay light side of the force.  Say Emperor go after every Jedi knight get his hands on comes list problems. Follow being first Dark sides light saber duelist are normal better light side light-saber dual need us at least some dark-sides of the force.  Even not be turn to the dark-side in process.  Last thing Emperor going want is rival. Such point willing put himself to harm way to prevent Star War Clone wars.  Jedi own reason not want a kill Vader under such policy worry replacement.  Vader been perfect fit for Emperor who want best body gaurd possible he best pilot galaxy and saber skill effect protect the Emperor against most foes. Emperor get replacement that replacement will better train using dark sides force been more lethal against.

Problem this idea first why Yoda and Obi want train Luke to take out Vader. On other hand he might able take out Emperor as will.  If two dual we no idea who would have own. It is possible Luke powerful enough take out the Emperor. They using fact Vader was his father to there advance against Emperor.  Second problem did not see elite Jedi strike force carry attack against Emperor. Means extremely secretive doing mission own.
