consider below text:
Throughout literature we find recurring tales of forthright people who are outspoken in condemning illegal practices only to be brought low themselves when they, or members of their family commit such acts.
As I search, I found that (given to here) to be brought low means decline of someone's position, credit, or dignity.
I think, the writer tries to make the point of "These guys, when one of their family commit such acts, They only bring low themselves "
I have tow questions:
Am I right about the author's intent ?
I cannot understand that only in the middle of the sentence. For me, it is more sensible to write sentence having pattern of that "X only when Y ". I am confused about the structure used in the original text.
