The next blessing is a bit complicated. It is believed to have been introduced after the inception of Christianity, and partly in response to it:
Let there be no hope for informers, and may all wickedness instantly perish; may all the enemies of Your people be speedily
extirpated; and may You swiftly uproot, break, crush and subdue the
reign of wickedness speedily in our days. Blessed are You L-rd, who
crushes enemies and subdues the wicked.
Since Christianity splits the identity of G*d into the Trinity, it represented a form of heresy to mainstream Judaism. There have been many others since then.
Instead of sectarian conflict, I choose to see this blessing as a channeling of our negative emotions towards our enemies, real or perceived. Note that it is the wickedness which should perish -- not the enemies themselves! We do not wish death upon our enemies: We wish for them to be cut off, subdued, and turned to righteousness.
How timely in this season of political and religious conflict!
