Answer:
I go around in circles, but always straight ahead. Never complain, no matter where I am led. What am I?
The more of this there is the less you see. What is it?
I am known for my natural tuxedo and marching
When I live I cry if you don't kill me I'll die.
Use me if you really want to see inside someone
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
