fighting the unfair fight

Such a cliche thing to say that life is unfair but, it is undeniably so. It was unfair, it is still unfair and it would be unfair. How do you fight such unfairness? 

I thought everyone including me was capable to fight unfairness however, it was a but a naive thought. I thought if I was honest, I was true and I was good I can battle unfairness and win. 

Sadly, I found out it is not so. 

Some people would always find successful ways to get what they want by extorting someone. And they even get away with it. They are not held accountable for their actions and consequences. 

The loss is only one sided. 

So, the question remains how do you fight unfairness? 

Do you fight unfairness with unfairness?

Or do you wait for redemption and not do anything and suffer the result of their unfair means?

Do people like that even get redemption?

One thing is certain: life is unfair.
