I think dysfunctional is also insufficient because functionalism can come under heavy debate.

How to formally state that parents have not raised their children well
For example these classes are abstract Mage_Catalog_Model_Abstract,Mage_Core_Model_Abstract etc.But it contain only defined methods.and what is the necessity to given class as abstract.
I know abstract class how to declare and rules.But i need more real time example(like magento).
Even i deleted abstract keyword before class name.but its not giving any error.
thanks in advance
