[Star Wars] Did Luke accomplish anything by going to Bespin?

Rewatching Empire with some friends, and Yoda just told Luke that he shouldn't go to Cloud City. I've been thinking about what happens in the rest of Empire and ROTJ, and here's what I imagine would happen had Luke not taken Vader's bait:

* Han Solo gets frozen in carbonite and given to Boba Fett (no change)
* Leia, Chewbacca, and and C-3P0 get left on Cloud City with Lando (a change, but not insurmountable for Luke and the Rebels to correct)
* Vader eventually gets bored of waiting for Luke and goes off to look for him (biggest change, with the most unknown side effects)

**IF** that's how things went down, it seems like Yoda would have been right: Luke should have stayed on Dagobah to complete his training. The biggest way I could imagine things going worse, if Luke had stayed on Dagobah, was if Vader realized Leia was his daughter/Luke's sister and decided to try and sway her to the Dark Side. Obviously that would make for a much different, and presumably worse, SW universe. Although I'd love to see Luke and Leia in a really good force fight...

Thoughts?

**EDIT** - How could I forget? 

Darth Vader: "Calrissian. Take the princess and the Wookie to my ship. "

Lando: "You said they'd be left at the city under my supervision!" 

Darth Vader: "I am altering the deal. Pray I don't alter it any further."

So, if Luke doesn't come, Vader eventually gets bored waiting and leaves Bespin...taking Leia and Chewie with him. Sucks for the Rebels!

Had he been more powerful a Jedi, he would only have defeated his father more easily. 

At the moment on the Death Star when he has Vader on the ground, disarmed (in both senses of the word), Luke does not pause to look at a bionic hand. He is untouched, unscarred, untroubled. He kills Vader. He succumbs to the Dark Side. 

The confrontation at Bespin is necessary for Luke to halt his tumble to the Dark Side. Luke's fatal flaw is recklessness; but it is deep in his heart, it is part of him: it is tied to his soul. It is fitting that it is his most human act, the act truest to himself, that will stay his hand at the crucial moment. 

Darth Vader was prophesied to bring balance to the Force. He does it at Bespin, by defeating, humiliating, and shocking his rash son. It is an act of misguided love, driven by narrow-minded certainty and self-confidence - the same flaws we see so starkly in the Anakin of the prequel trilogy.

By being true to himself, Darth Vader plants a seed that allows Luke to be true to himself. And in the end, Anakin fulfills the oath every father takes: he sacrifices his life and more importantly his view of the world. He helps his son become who he must be, no matter the cost to himself. He heals himself by healing his son.
