Rainsford's actions are justified because he will never truly be free until Zaroff is dead. A "beast at bay" refers to someone who is still being hunted. Rainsford will always feel hunted as long as Zaroff is alive, because he knows the 'hunt' will always go on in Zaroff's mind. He has to kill Zaroff so he doesn't have to live in fear.
Is this about a book orrr what? like a story?
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The settlement that was also founded by religious reformers, but NOT as a break from the Church of England, was the Massachusetts Bay Colony in 1630.
We are talking about the Puritans, who were reformers too, but in a notorious difference to the Pilgrims, Puritans were not separatists, they did not separate from the Church of England. They preferred to reform the church from the inside.
So when Puritans founded the Massachusetts Bay Colony, they followed their religious teachings and methods without splitting from the Church of England.
