Because they’re fucking retarded. As Joker said wisely, “If it was me dying on the sidewalk, you’d walk right over me.” A man like us could express our feelings of grief and anger at the terrible world we live in, in the most poetic possible way, and people will make fun of you and claim you’re acting like a man from a time period where people were intellectually superior. Everyone is now desensitized to evil and live life like robots programmed to follow the crowd.
