Hero vs Villain

How do you convince people that you are not the villain, but instead you are the hero?
Why must a person fall in either category?
Are we not all villains and heros in our lifetime?
I guess it all comes down to intention.
If your intentions are good then you must be the hero right?
But intentions can be hard to read.
And do villains not trick the good to believe that they too are good?
Well, then how do you tell the difference between good and evil?
You must have faith that a person's intentions are good and then he will become he hero in your eyes.
Faith, yes. Blind Faith, NO!
Judge a person not by his words alone, but by their actions.
Its been said many times, actions speak louder than words.
