It seems it is pointless since we just have different opinion on the whole matter.

It may be pointless but there's no harm in civilly discussing a topic.

I find it interesting in your response to Ryan you only mentioned "his plan". "Plan" again. And so on. You say you understand the emotions going on in the scene, but you didn't reference any. You simply kept coming back to an agenda, as if Vader is a static character merely trying to succeed in his goal.

What I'm trying to point out is that, unlike Star Wars, Vader's character is not presented in a static way in Empire. There are a series of setups and payoffs that painstakingly try to humanize him and make emotional changes in him plausible. Entire scenes and lines of dialogue earlier in the film were specifically created so that Vader would seem like a human being capable of vulnerable emotions by the end of the film ... but you are arguing that he was a 2-dimensional "calm and cool" character just trying to get his job done.

It's clear the scriptwriter did not feel the same as you. And if you listen to the subtext conveyed through the changing intonations of Vader's voice during the Bespin duel, it's clear James Earl Jones did not agree with you. And if you listen to the increasingly explosive sound effects and visual fx during that duel, it's clear the people creating those effects also espoused the view that Vader's emotional outburst was growing and swelling as the duel proceeded towards its climax.

It's highly unlikely that all of those people shared the same interpretation by mere coincidence.

All in my opinion of course.
