I assume you mean "given to his animals." If this is the case, two important elements are the human capacity for both religious and political blindness
Religious hypocrisy is found particularly in Moses, the Raven. "Moses preaches "the existence of a mysterious country called Sugarcandy Mountain, to which all animals went when they died;" in that distant land "it was Sunday seven days a week, clover was in season all the year round, and lump sugar and linseed cake grew on the hedges." Obviously, when the story is played out, the reality is certainly nothing like what Raven promises.
Political hopes for utopia are also lambasted. The propensity of human beings to blindly follow the crowd is perhaps the most important theme of Orwell's novel. As the notes here at eNotes rightly point out, "(t)he only protection the average citizen has against a similar tyranny developing in his own country is his refusal to blindly follow the crowd (like the sheep), the repudiation of all spurious explanations by propaganda sources (like Squealer), and diligent attention to all government activity, instead of faithfully following those in power (like Boxer)."
