I thought of something random at work today.
If anyone has ever seen the cartoon Wacky Races then they would know that Dick Dastardly is always being called a cheater.
My though was that they always called him a cheater, but the others would cheat as well. I suspect that it's because he stops to cheat.
Think about it, all the other cars had devices that essentially allow them to cheat. Take a look at the Gruesome Twosome for example. They have a ghost that they use to scare the other racers, now how the hell is that not cheating? Or Professor Pat Pending, his "car" can turn into anything. "Oh dear the road has just suddenly turned into a lake. I'll just turn my car into a jetpack." Because we all know that it's still a car race when you're using a jetpack.
Essentially the entire race was a bunch of cheaters cheating their way to victory. (A notable exception would have to be Peter Perfect, whose car was just that, a car. And it usually fell to bits because of it.)
But Dick was always the "cheater". But maybe there was another, more sinister reason for it.
In order to cheat as much as he does he would need money. Since he never wins any races he would probably run out very quickly.
I think therefore that he would have been paid by the Wacky Races people (if such an organisation existed) to cheat to make the races more interesting. There is no other reason for it. If he is able to get a massive lead every race (and several times too) to set his traps then it stands to reason that he could, you know, just race normally and win.
By scapegoating him it also allows the people to claim that the others don't cheat, because you have to stop and do something in order to cheat "properly".
So that's pretty much it, Dick Dastardly is a scapegoat, but he's also part of a massive conspiracy that involves him being a scapegoat.
