Don't sugarcoat it. You make Bart Simpson equivalent to Charlie Brown. The truth is, Bart Simpson is much worse than Charlie Brown. Here are some indefensible things Bart Simpson has done:
-Destroy Lisa's Thanksgiving centerpiece
-Shatter every glass window in Springfield with twelve police megaphones all lined up
-Steal a police car and crash it into a tree
-Shake up a can of beer with a paint mixer, which triggered an explosion that blew off the roof of the house when it was opened
-Flood Springfield Elementary School from top to bottom with a fire hose
--Make Lisa look like a psychopathic babysitter in hopes of ending her babysitting career
-Trick everyone on a cruise ship think they had to stay at sea forever because the whole world was overrun by a deadly incurable virus
I could go on, but I think you get the point.
