Summer’s Night

You may enjoy me on a summer’s night,

While other’s prefer to fight.

In many people’s homes, I am generously fed

Unless I show up uninvited.

I never stop being hungry

and consume anything that lies before me.

In fact, I am hungrier after I ate than before.

Striking me will only anger me more.

People create me.

But they won’t let me go free

Terror I often bring

For I can destroy almost anything

Many people need me to live

For the many things I give.

Although I can show you your way

You can only hope where the end of my path lay

What am I?
