All of this is your own personal headcanon. Which is fine, but let’s not pretend like it’s factually correct. And while I know wookieepedia is far from a perfect source, it at least tries to get as close to the canonical truth of the often contradictory backstories of characters in Star Wars media. On the page for Anakin Skywalker, one section starts

Believing that he lost all that he cared about by his own hand, Darth Vader embraced his role as the Emperor’s chief enforcer. Few knew who he was, and even fewer suspected that he had once been Anakin Skywalker. Some rumors circulated that Vader was a counterpart to the late Separatist warlord General Grievous, whom Palpatine had held in reserve, while others speculated that he was a technologically modified warrior trained in the now-forbidden arts of the Force. His appearance at the Imperial court and the favor he carried from the Emperor earned him the distrust of Imperial officers. They resented him for appearing out of nowhere and having authority over them because of his link to his Master. They also resented his heavy-handed treatment of them, such as when he used the Force in the presence of his Master to choke Colonel Barokki. In secret, Barokki and another Imperial officer plotted to assassinate Vader, whose position in the new Empire they did not understand.
