Grandma apparently does agree that two wrongs can make a right. Throughout the book she has no problem lying, cheating, and even blackmailing people to get what she wants. However, since her intentions are always good she believes the ends justify the means. For example, she misleads the banker's wife into believing that Abe Lincoln stayed in Effie Wilcox's house in order to keep the bank from repossessing the house and tearing it down. She also planted a dead mouse in her milk bottle so the dairy farmer would be obligated to punish his delinquint boys for their mischief. Her outcomes are always desirable, so she is viewed as somewhat of a hero because of her actions.
