Did Darth Vader actually turn good at the end of Star Wars? Yes. The conflict within him that Luke felt was his love of his mother and Padmee, as well as the good he did as a Jedi. His friends among the clones such as Rex and Fives and his apprentice Ashoka.
The added risk Darth Vader takes in allowing children to live in a situation where he could have killed them proves that he regrets killing Younglings and will avoid harming any more children for the rest of his days, though intense intimidation is a dark strategy to avoid repeating his Youngling massacre.
Slaughtering a village of Tusken Raiders. Letting Darth Sidious kill Mace Windu. Killing the Jedi and the younglings. Being responsible for Padme's death.
With that being said, if Palpatine did, indeed, use Force-healing to keep Vader alive, he didn't appear to have given enough life force for it to take a toll on him -- and being as close as Vader was to death, Palpatine would have required a lot of energy to keep him alive.

Why did Vader hate Palpatine?
Darth Vader Hated Palpatine More Than Even The Jedi
For all the hate he directed upon himself, he'd come to hate his master just as much if not more, especially after learning that Palpatine had kept the truth about Padmé's death from him for so many years with the reveal that Luke Skywalker was his son.
Vader hated himself. It likely only grew worse when Vader realized that Palpatine had absolutely played him. The comic series Star Wars: Darth Vader: Dark Lord of the Sith (by Charles Soule, Giuseppe Camuncoli, Cam Smith, Joe Caramagna, and David Curiel) picks up immediately after Revenge of the Sith.
In the main Star Wars timeline, of course, Darth Vader's attempts to resurrect Padmé on Mustafar were doomed to failure. But it's fascinating to speculate what would have happened had he been successful. In that scenario, Padmé Amidala's return from the dead would not have provided the solace Darth Vader sought.
Granted that it had just been a year since their last match-up, but the body's deterioration can rapidly increase as someone gets older. Coupled with the fact that Anakin had long been reliant on his armor which means that in reality, he's in worse shape under his suit than he might appear in Return of the Jedi.
When rage and anger seethe inside a dark side user, their eyes may burn yellow with a fiery-red rim." What that means is a Sith's emotions will be shown through their eyes. A Sith's power level can also be determined when their "Sith eyes" are visible.
Qui-Gonn, although having begun practicing the art of becoming one with the force, did not complete his training, and so still desired to finish this, meaning he was not at peace with himself. Vader had done too much bad during his lifetime to ever be at peace with himself, meaning his body did not disappear.
Vader constantly regretted what he had done - he knew he made an unbelievable mistake. But, he also knew that it was much too late to change anything. He had to live up to what he had done - and the best way to do that was through embracing his hatred and anger, letting it grow and fester in him.
However, when it comes to who Darth Vader hates more than anyone in the Star Wars galaxy, himself and Obi-Wan Kenobi don't hold a candle to the true point of Darth Vader's hatred, Emperor Palpatine. Star Wars: Darth Vader #39 by Marvel Comics is available now. Please verify your email address.
The novel explained that, had Vader killed Obi-Wan on Mustafar, he would have tried to kill Palpatine too, but given how badly wounded he was after the duel, his power wasn't the same and he was weak, both physically and mentally.
The third film in the original Star Wars trilogy ends with Vader protecting his son, Luke Skywalker, by throwing Palpatine into the Death Star II's reactor.
So, if not Palpatine, who could Vader possibly fear? Well, the answer is deceptively simply, yet incredibly shocking all at the same time: Luke Skywalker.
The obvious explanation comes down to poor overall planning. While James Earl Jones voiced Darth Vader and David Prowse played the villain in costume, Lucasfilm brought in Sebastian Shaw for the unmasking scene. At this point, the English actor was already 78 years old.
There are plenty of moments throughout the franchise where it is clear to see that Darth Vader still has some good in him. However, that full turn back to being a hero doesn't take place until he picks up Emperor Palpatine and throws him down the reactor core shaft.
