Try to separate what happens in Jedi from this for a moment since those events haven't happened yet. At this point we don't know conclusively that Vader is Luke's father- neither does Luke.
Just suppose that in the next film, Luke had a conversation with Ben in which Ben finally revealed "the truth". Vader was lying to Luke, and the only reason Luke was fooled was because, not being fully trained, he hadn't yet perfected guarding his emotions and desires (part of him wanted to believe Vader). Also because he was badly injured (his hand was chopped off) his psyche was easily compromised and he was close to being completely seduced by this master of lies and evil. The actual truth is Vader did kill his father as Ben originally said. And his father was not only the brother of Owen Lars but... a brother of Ben Kenobi himself! All three were siblings and Vader has slain all three and is now after Luke to defile the bloodline completely because...!*
Put aside 30 years of poorly told prequels and non canon books and comics and shifting answer interviews with Lucas and ask yourself where in the first two films (SW and ESB) would this kind of revelation have been an impossible contradiction?

Nowhere.

What does this exercise prove? That the telepathic signal at the end of ESB is no more a sturdy example of empathy building between Vader and Luke than the force choke between Vader and the senator on the Death Star in the first film. It could be spun a completely different way if it needed to be- for example as another display of Vaders overwhelming powerful mastery of the dark side of the force.

So without that, we are now left with only the events of Jedi to support these last minute changes of heart. Essentially what we are getting is a whole lot of justification bundled together in the third act (Jedi), for everything that is about to be contradicted from the first two acts (ANH, ESB).

And every example that you cite here, of how Jedi supports these coming contradictions



All these are examples of the film TELLING us this is how Luke feels, but not showing us that these stated feelings are in any way warranted.
An example of showing these statements/feelings being warranted would be something like a scene (In ANH or ESB or even the first act of ROTJ) where we experience Vader having the opportunity to save/protect Luke and his friends and frustrate the Emperors goals and does so.
Where in SW or ESB has he ever done this? Actually what we experience is him doing just the opposite in ESB by capturing Han and Leia and torturing Han to get Luke into his clutches. THAT is what we see and experience about this character...not that he a good, conflicted man struggling to get free.
Or how about a scene where he is shown deceiving the Emperor in acts 1 or 2 (of Jedi) for his own purposes? Something like that would support his previous petition to Luke at the end of ESB that they join forces and overthrow the Emperor because we now see proof that is what he wants to do.
There isn't anything like that anywhere in the film! Vader was full of shit on Bespin because the very next film he is shown to be a completely in the service of the Emperor- as he has always been- executing every order he is given without fail until this 11:59 switch where he suddenly, out of thin air, develops a conscious.

Luke swaggers into Jedi announcing to the world this master of evil is his father and therefore he must be a good man and is worth a sacrifice to try to redeem.
And this is what the Hulk Critic is talking about when he discusses ASSUMED EMPATHY.


In the Jedi example, Luke is the (supposed) hero and that's why we are supposed to share every feeling he tells us he has- not because we see events play out dramatically to make us understand and let us experience ourselves why these feelings exist (i.e- why Vader is good, why Luke should sacrifice himself for him, etc). Just because he's the hero and he says this is what he feels so we should feel it too.

And these are the exact same mistakes MoS makes again and again

All three were siblings and Vader has slain all three and is now after Luke to defile the bloodline completely because...Vader was lusting after Anakin's wife (Luke's mother) and this sexual jealousy is what precipitated his turn to the dark side and why he ended up killing Luke's father. This is why the episode in the tree alludes to Luke becoming another Vader- that his rivalry with Han over Leia is what could lead him to the dark side just as well, should she spurn him and choose Han- if Luke is unable to accept it and move on.

Honestly- is any of that worse than "oh by the way, Leia is your sister and Vader is your father.
Wow! you're right. Now I suddenly feel empathy for him and will try to assist him in redeeming himself. I'll also just ignore all the evil he has done up till now because he's the daddy I never knew so he must be a great guy underneath it all...despite all that cutting off my hand and repeatedly torturing my friends and sister stuff"

Which of these two scenarios is actually supported by the actions, events, and character behavior we have seen & experienced in ANH and ESB and which scenario is consistently contradicting those same actions, events, behaviors?

Nowhere in ESB or ANH do we see Vader act in a way that can be construed as conflicted. He has marching orders from the Emperor and he carries them out...in both films. Every action he makes on Bespin conforms to the plan he hatches with the Emperor in the second act of that film to capture Luke. Further he chops his hand off and tries to seduce him with appeals to blood ("you're my son, let's finally be together as father & son) and power ("we'll rule the galaxy together!") but neither of these appeals is inconsistent with his evil persona. If he can't capture Luke by brute force, he will capture him by seduction and vice versa. Just because he fails and Luke escapes doesn't mean that Vader is actually good or conflicted about his actions. His attempt to reach him telepathically was in the effort to control his mind and get him to overpower his friends and turn the Falcon around so that he could be taken into custody...nothing more.
After two films full of dramatized evidence to the contrary, you are choosing to rationalize that one act as Vader making an honest sympathetic appeal? You're reaching to find any feeble evidence of anything in this character to support characters suddenly adopting attitudes in the next film that are entirely inconsistent with their past film experiences and fully unearned.
