Riddle 9

My new riddle your brain will tease
Or can you solve this one with ease?
I'm the fact you cannot deny
And no matter how hard you try
I'm always walking at your side
And find you wherever you hide.
Simply seeing me leaves a trace
I am brutal, I am full of grace
War and peace mean nothing to me
And From me you can never flee
Often wished on others instead,
I'm the one justice you do dread
For to me, you're all the same.
Now, can you guess my name?
