Is manipulation evil?

[Boromir88]

Firefoot:

In and of itself, I would not say manipulation is evil. It is the motives of the person doing the manipulating and the way they do it that makes it evil or good.

But is it something related to the argument about "Pride." (click)

Where there is a "good pride" (Confidence or Pleased), and there's a bad pride (Arrogance). In this case there's a good persuasion (persuasion-Gandalf), and a bad persuasion (manipulation-Saruman).
