Living the Good Life in Prison?

I live in a dark place,
In a four by four room
White walls
Trapped in bars.
The dargest place that a man
Will find himself in,
But I get treated pretty well
For what I have done.

Everybody knows me here
But I don't know myself.
I don't have any freedom
No rights
I deserve it.
I'm an animal;
I have killed my wife Nicole
The one woman I lived for.
I am too embarassed of my kids to see me here
To know what I have done.
They will hate me;
I have killed their only mother.

But she made me do it
I really didn't kill her.
