Who Is Good? What Is Good?

I've always wondered
What is good in our choices?  
What is bad in the decisions we reason through?  
Every action, born from thought,  
Feels right   to the one who acts.

Yet still,  
Everyone desires to be called righteous.

The hero saves the world from the villain,  
But in doing so,  
He often mirrors the villain’s hand
All in the name of good.

And the villain?  
Yes, they harm, destroy, and take.  
But even they justify their cause
Claiming to serve justice,  
Or help God correct a wrong.

So who decides?  
In whose eyes is the villain evil?  
In whose truth is the hero pure?  
We live in a world where things  
Must always be  good  or bad

But perhaps,  
We just choose sides
And call it truth.
