   Summary

   It’s ironic how one’s plan of goodness, a grand gesture of kindness; can become skewed by an outside view, tainted and seen as something vicious and menacing. So much so, the lines become blurred from right and wrong for a person who had only wanted to do only good. The public unable to view them as anything other than a corrupt villain. A person who wanted to save the world, not to burn it.

   Well…Watching the world burn a little before putting the flames out, wouldn’t damn it any more than it already was…
