How could the "mistaken kindness / identity" match the operation of -ed

Sorry -- your question is inscrutable! Could you explain what you're asking about?

I am sorry if I confused you.

Thank you for your continued help. (here a question again, why an adj. ends in ed ?)

I have to display the way of reading the "-ed":
This sentence: He is justified in asking her for her resignation.

[He is justified] means that this line come out of the other's mouths-----{coming in from the outside to the inside}, that was a judgment a

mistaken identity: Someone outside the story made a mistake in the identity of someone inside the story. He is outside the story, so we don't know who he is, but he made the mistake.

Hi CJ,

I think you are a good man for it, because it come from you.

[mistaken identity]------(my version) = the identity is mistaken in identity; The reason for using -ed is that the expression is of a judgment sentence and the speaker is not the identity but a judge man.
It is similar to : I justified the thing. (not a judgment) ; He is justified in the thing. (a judgment, "

Let's see a judement and not a judgment:

1) I think you must be mistaken about this thing. (a judgment and the real activity is "this thing" in which the judgment about his behavior is made. So under the power of the real activity---about this thing, you must mistake must change into this way of "you must be mistaken" )

2) I think you must mistake this thing. (not a judgment)
