Was Luke's character assassinated in TLJ?

I don't understand how Luke with his lightsaber standing over young Kylo would automatically send Kylo to the dark side. Even if Kylo did have dark side tendencies that seems bit of a ridiculous reason imo to completely turn from good to evil.

It would have been better if they had just stuck to what Episode 7 was pointing to that Kylo just became obsessed with his grandfather Darth Vader and thats why he went bad. Not because Luke had a vision and thought about killing his nephew. That is so unlike Luke and was really dumb imo.

 

Luke standing there with the saber was the tipping point. All the other stuff that was suggested had already happened.

 

The weird thing is Luke felt his father Darth Vader was redeemable but his own nephew he can't do the same? Instead he goes psycho and has thoughts of killing him. That made no sense.

 

I think it made sense to me because I read Luke's instincts about Vader differently.
I would say Luke's idealistic stubbornness (I can't: it's too big / I know there is still good in him / Preferring death over submission twice ) is the actual character trait.
The fact that his idealistic faith got rewarded at the end doesn't mean that trait will always lead him to the light from that point on.
Being so freaked out by darkness in Ben to probe his mind and then being overcome with a fleeting urge to prevent history from happening before it happens is exactly
the kind of thing Luke would do.

 

We don't know what Luke saw in his mind but it must have been pretty earth shattering for him to act like that.

We'll just have to wait and see if Ben is redeemable, but it's not up to Luke to fix it this time
.
Luke went out like a hero saving the resistance.
People saying that he's not the Luke Skywalker they grew up with need to be reminded that people can change through the course of their lives.
Especially after some traumatic event.

Sometimes they can become weak and they just needed a push in the right direction to set them straight again.
Luke had that push from Rey.

Luke Skywalker is Not an infallible hero, and by making mistakes and needing help he became much more real to me.

 

But Luke did try and kill Vader - when Leia was threatened. The argument that he can never be susceptible to the dark side in this way again, even fleetingly, is wrong and unfair.

Luke had a moment of madness because of what he saw in Ben. But what was worse for Luke was the fact that he had missed what was happening to his nephew. He blamed himself more for that than anything else - he should’ve seen it but because of his hubris he failed and Snoke corrupted Ben.

 

It seems some people are missing the point. The contexte is wholly different.

Luke and Darth Vader: Vader is this terrible evil guy and was this evil guy even before Luke was born. Young, idealistic, naive Luke dream of saving the galaxy from evil. He insist that there is still good in his father and thinks he can convince Vader by talking to him. He fails miserably. Vader exhibit his the full extent of his evil when talking about Leia and Luke almost fall to the dark side as a result. Realising just in time what is happening, he prefers to sacrifice himself than become another Darth Vader. Vader witnessing Luk’s sacrifice decide to kill the emperor and saves the day.

Luke and Ben: An older Luke still idealistic dream of starting the Jedi order again. Everything seems fine but despite his best efforts, one student, Ben is seduced by the dark side. The problem is that Ben really want to become the next Darth Vader. Luke see this, know that there is no redeeming Kylo Ren and realise that he is the creator of the next Darth Vader. So not only Luke failed his nephew and his family, but he also brought death and destruction to the galaxy. He is the source of evil this time. As for the « murder » thing, it’s a short fleeting of thinking that killing Ben will prevent millions of death, but is horrified by what he is about to do and stops.

 

Luke simply changed his form, now as force spirit is much stronger.

 

AND he still almost killed his father. Also, it's a different situation, he felt he could pull Darth Vader back from the dark side... Vader had already destroyed so much. Ben was about to destroy all that he had built.
