I want to describe the action of a person who is fed up with the many compromises he has made and now would like to "remove" these compromises he hates - what is a verb that means "remove compromises"? Abolish?
It is common to say that a person accepts or rejects a compromise. A person who accepts a compromise could later reject it.
"Abolish" is not combined with "compromise" in place of "reject", according to Google Ngram Viewer.
Some potentially relevant collocations are: disavow, repent, repudiate, brook no, reject, and eschew although some of them are admittedly future oriented rather than the backwards looking meaning the question implies.
This question is so broad-based there's no definitive answer. The best I can come up with is...
I'm fed up with always compromising. Henceforth I resolve to be more assertive.
I don't think there is a word for it. Just invent your own.
