The problem is you could say the same thing about aspects of capitalism. Look at any mega corporation, are the employees treated like people or worthless numbers? Wal-Mart is a great example. The military also falls into that "worthless numbers" mindset as your rank and file grunts will be sacrificed when necessary as "acceptable losses" if the ratio of dead to alive is considered acceptable to complete the mission.

Evil can be present anywhere, so using that as a justification can be tricky. Would you say that the Catholic Church should be torn down because they have a pedo problem in their priesthood, or should those doing wrong be rooted out and the overarching system saved because the core aspects as told in the bible are still good? Failure is one of the few things that can be checked against any system and always shows results.
