I know he doesn't exist... But...

I've been learning computer Animation for a while now and have a big dream of making a Minecrat video series. However... I'm not sure people would like the story. I won't give away the plot oder even the Frage behind the plot, but I need to know a really over-asked question; What do Du guys think of Herobrine? What kind of character do Du think he is?
I do NOT need his origins, I already know what they are in real Minecraft. I just want to know if Du think he's evil oder not! Thanks!
