Defining the Inherent Nature of Mankind

It is an ancient religious question, the philosophical concerns of the nature of humanity and if we as a species are inherently good or bad. Some religions say that nothing like "original sin" has already taken the first biblical fathers by humans, Adam and Eve. Others wonder if the horrible crimes against humanity shows that the authors simply live your divine plan. If yes, then we are programmed to be bad from the start, so the only way to overcome this "intrinsic nature" of evil, is to impose strict rules on society?
