As the readers all know from the beginning, most of the animals are not able to read or write. They ask for help to read the commandments and simply follow what the commandments say since they do not have enough knowledge to rebel. Napoleon knows that they cannot read or write, and so, he deceives all the animals by just adding a few words to the commandments. Since the animals are not literate, they would of course not remember what the commandment said. As Napoleon adds some simple words such as "To Excess", nobody would realize that there had been a change. Truthfully, the animals in the animal farm are not stupid, but their disability to read and write has been an advantage for the people who are literate. It is a very evil act for the government to take such action, but if the animals were able to read and write, the government and Napoleon would probably have been overthrown by now (since there are a lot to complain about for deceiving the animals). Rather than just lying, Napoleon should notify the animals so that there would not be any complaints in the future (if the animals notice), and convince the animals for the reason why he had changed the commandments.
