Who Am I?

I am many things, you are....

WHO AM I?
I am the drug that saves you or kills you.
I am the spirit that helps you or haunts you.
I am the man who walks all paths.
I am the best result of the worst past.
I am known to be illegal.
I am known to be hated.
I am the one who knows the most.
I am the one who lives through all.
I am the love in your heart.
I am the hate in your fists.
I am immortal.
I AM KR0NIK
