Some disagree with me, but I think that there is substantial evidence that Dorothy Gale of "The Wizard of OZ" is a remorseless and careful witch killer. I would suggest that perhaps Dorothy herself is a witch who is jealous of the witches of the East and West.
(Text taken as it was told to Dorothy's jury in murder trial...)
From the beginning of the story we see that Dorothy is one who wanders in and out of reality. She displays acute mental unsoundness. Dorothy takes the risk of walking on the fence when there are evil flesh eating pigs beneath her. When she falls she does not scramble to get out, instead she wallows in the mud with the sows and waits for someone to save her and thus demonstrates her need for loyal, slave-like servants. (A characteristic of a witch) This self destructive behavior is proof of her unstable mind.
Dorothy runs away from home because she is seeking bigger and better treatment. Her family is not good enough and there are all of those evil citizens out to get her...and her little dog too.
Dorothy claims to have been swept up in a tornado and flung about and to have been dropped down on her first victim of the story. If you have seen footage of tornado destruction, you know that tornadoes do not carry entire houses without splintering them and shredding them into small pieces. With this in mind, let us consider that Dorothy owns some supernatural force and has some extent of control over the flying house since the house has allegedly traveled for many miles in the sky and the only damage done is some possible breakage of a door hinge. With this extent of power and control I would only assume that she would also have enough influence to persuade where the house lands.
In Dorothy's trip across the threshold of reality and fantasy, (the part that she claims to be the tornado) we see images of her mind drifting by outside. Here it is apparent that she feels taunted by the witch as she cringes at the witches innocent and frienldly laugh.
This is evidence that Dorothy is threatened by the other woman and apparently has enough power to do something about it. Her solution, kill her! So Dorothy Gale of Kansas throws a house down upon the witch. As a sign of her deed, Dorothy takes a token, a "souvenir" of the killing, the witches shoes. An act as evil as an indian taking a scalp.
In the second murder, we know that Dorothy has motive. She is angry, she is looking for someone to lash out at, furthermore, Dorothy beholds the witch with disgust. Not only because she is sister to her first ever so hated victim, but because the witch is trying to take away her prized trophies.
Dorothy claims to have been helping a friend on fire. Let us consider that Dorothy did not know the contents of that bucket. As eyewitnesses we know that she did not fill the bucket nor did she have an opportunity to test the chemistry of that container. Dorothy was negligent in tossing that container. If she knew not the contents, then she had no business using it as a fire suppressing material. To the best of her knowledge, it could have been gasoline or sulphuric acid.
Even as the witch melts Dorothy shows no remorse. She could have offered a handkerchief or if that not be available, a piece of her clothing would have been enough gesture to suggest that the act was unintentional. Once again we see that Dorothy must carve another name onto her sword as she steals the witches broomstick.
