Every created being is good naturally, When God finished His six days of work He said that every thing He created was good. Badness which is vice is only accidential to human nature, everyone is seeking what is good to him, even if sometimes badness can be their means of misunterpretation of what they take as goodness, to come to the end, which is their own goodness. Every one is good by nature and tends toward goodness. Some, as the devils seek only to be bad and maliciouss, evil, it is their way of expressing their obscure, and mysterious way of saying I am happy.
