I enjoyed reading this very much and hope you'll write more as your style is promising. I also like the way the text isn't just full sentences but also fragments and bits where the speaker changes his course of thought and such. Effectively the speech is much more realistic and therefore more relatable and/or credible. Sadly, I don't see this often in amateur monologues.
The subject of the monologue is also good as it throws a different light on aspects of society, especially at the end, and provokes the reader/spectator to think after reading/watching.
Good work.

it's an interesting concept. and I can see both viewpoints - but I've never thought of a madman's point of view before. Good writing.

One small thing - when you wrote "their presence sacred me" I think you meant "scared me"
