Bureaucracy is self justifying, expansionist and confomist, as a rule any government should look to trim it during their mandate but that doesn't mean that it does not employ some highly ethical and fair minded employees. Like all human institutions it reflects the society it comes from.  Describing it as pure good or pure evil is an act of ideology.  
That being said, there are occasions where the premise of the bureaucracy itself is wrong and should be abolished. Historical examples would be the Ottoman office of religions, the German office for race aliens, etc..  In Canada, the Social Justice Tribunals have revealed themselves to be malevolent judicial dictators and should be abolished with their functions folded back into the traditional Justice system where they are more accountable.
