You may enjoy me on a summer's night, while others prefer to fight.
In many people's homes, I am generously fed, unless I show up uninvited.
I never stop being hungry, I 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?
