As if in dependent need of each other? Sorry, but no. I am not a Liberal so I would not speak of forcing by legislation, an egalitarian society, but we're all talk of how the world "Sucks" and how God doesn't answer prayers and now we say that there must be evil for there to be good?
Personally (Meme war aside), and this is my belief... one instant of evil is the cause of so much of it today. I speak of the sin committed by Adam and Eve. Just one sin, has infected and corrupted the whole world; our inclination for evil is also passed down from generation to generation (Genesis 3:1-19 & Romans 5:12-16).
A small example of this is Alcoholism. A "Perfect" family (with very young children), one day, can descend into a cycle of chaos the moment the father becomes an alcoholic. What ever weakness he has had comes to the fore; such as short-temper, and the young pattered their behavior after their dad. Thus, the cycle begins.
The children grows up twice as bad as their father (depending... we are all the product of our environment whether you agree with it or not); some more violent than the other, or the other more drunk, and when they marry (or not, but had children after premarital sex). The mistakes of the father, will almost always be passed down, if not checked quickly.
