Shakespeare's opinion on war

When I finished reading Macbeth, one thing that immediately stood out at me was that this tragedy, both begins and ends with war and bloodshed.  I think Shakespeare intentionally did this because as we've learned from the last books we've read, authors often try to impose their own beliefs and bring attention to problems within modern society.  I think that Macbeth is trying to really highlight the negative impact war has on not only the people directly involved in it, but others as well (evident by Lady Macduff's murder).  I would assume that everyone is against war, but few convey this idea more elaborately and revealing as Shakespeare.  As i started to look into this even more, I discovered that Shakespeare also questions the morals, ethics, justifications, etc. of war through other plays and I think this central theme was really highlighted by the beginning and end of Macbeth.

Another thing that i hate to admit it was that Lina was actually right and that the whole thing about Lord of the Rings was accurate therefore i owe you an apology.... but don't expect another one anytime in the near future.
