The Green Lantern went up against a Charles Manson based villain in 1970.
Maybe when we get you straightened out, we'll learn something... maybe we'll finally know how maniacs like Joshua can come to be... how they can seize the hearts of decent people and fill them with the poison to hate... of bigotry! Sure, the hypnotism was part of it... but there had to be a part of you that responded to his insanity -- you... me... all of us! Maybe now we can get rid of that part... forever.
Thanks to rfoglio for the tip!
