A Question Of Terror

Can you please explain?
How an act of terror is defined
A man battling an oppressor
Or oppression by a government
Can you please define?
What you would call right and wrong
Perhaps the same old difference
Between weak and strong
Do you understand?
That your life will never be the same
That the rules have changed
And those who hunted now are game!
With might you march and trample
What dissidents hold dear
But your weakness and Achilles' heel
Is that you live in fear
The only fear I know
The fear of my own mind
For all the times I have rehearsed
The slaying of your kind
