Who said death to all humans in animal farm?

In George Orwell's "Animal Farm," the phrase "Death to all humans" is attributed to the character of the pigs, particularly Snowball and Napoleon, as they promote the revolution against human oppressors. While the specific phrase is not directly quoted from a single character, it embodies the overarching sentiment of the animals' rebellion against Mr. Jones and humanity in general. The slogan reflects their desire for freedom and equality among themselves, free from human tyranny.
