Not only is blaming Snowball ruining his reputation at the farm, but it is also a method which protects Napoleon from any criticism because if anything goes wrong, the animals are conditioned to blame it on Snowball. This provides a convenient excuse for why things are going wrong. This tactic is particularly welcome during this time when food is short and there is a possibility of a rebellion from the hens. The animals cannot focus on what is really behind all the farm's misfortunes (probably Napoleon's mismanagement), but concentrate on the possibility of Snowball coming to the farm and night and causing mischief. This type of fear is the type that controls because the animals don't think for themselves. They merely believe everything they're told.
