Not Really Against Utilitarianism

Bernard Williams has some good points about the shortcomings of utilitarianism in "Against Utilitarianism", but the arguments he uses are off.  His example of George taking the job for biological warfare because he needs employment is not necessarily a good idea or a bad idea.  Williams tries to say utilitarianism is wrong because you can make the wrong decision if you think only of utility, but utilitarianism doesn't mean that you should only look to the utility of it, but you should keep the consequences in perspective.  The consequences could be that George taking the job leads to him becoming immoral in other aspects of his life.  Utilitarianism is a philosophy that recognizes the world isn't black and white and that a decision based on principle alone can easily lead to disastrous consequences.  Disregarding consequences in decision making can be horrific and if any rules are considered too important to ever break, that too can lead to horrific results.  It is wrong to lie, but surely there are cases where it is acceptable.  It's wrong to kill, but what if it's the only way to stop a serial killer?  Consequences should always be kept in mind, but one should be careful not to purely accept them because that can lead to a lack of humanity.  Nielsen emphasized this and he did a great job of explaining how it may be more practical to let something inefficient to happen (such as the mob violence) rather than infringing the law because it could actually lead to a breakdown of the moral structure and legitimacy of the political system of the state.  Utilitarianism does not mean just doing what is most efficient in an individual situation, but rather making sure that you look at the situation and make the right decision based on the real world and not ideal principles.
