Consequences Of A Sadistic Nation.

The conclusion of "The Lottery" is very ironic and unexpected by many.  This scenario could be compared to christian priests that do all they can to "save your soul" and even if you don't believe that there is a higher power they try to twist your mind into what they believe because they believe that it the right thing to do without considering the consequences that it may have on the person being indoctrinated.

This could be also related to "The Perils Of Indifference " in the sense that while the genocide was taking place the world felt very strongly against it but just sat back because it was inconvenient for them to help.
