This literary device is an example of "foreshadowing" - an indication of how future events will be effected.

The best example of this is colonial
India, where several famines happened under British Rule, being the
first major of it in 1770, in the region of Bengal, where about
a quarter or a third of the population starved to death in a ten-month
period, and East India Company's raising of taxes to farmers
disastrously coincided with this, exporting
the majority of the crops to Europe, and leaving poor most of the population that was employed in agriculture in that moment.
Answer: Very few groups in the 1960s advocated violence, except the US government, in the form of military adventure, where they went far beyond advocating. A total of about 1,353,000 deaths occurred on all sides in the Vietnam war. Then there was/is the Klu Klux Klan. We need to be watchful even now. The Weathermen were a small organization and they claimed not to intend violence, but use it if “necessary.” The Black Panthers called themselves a party of “self defense.” Whether or how often individuals in the latter two groups deviated from their charters (if any) is hard to determine.
Anyway people can justify their actions of violence it doesn't mean it was justification for everybody.
