"Hatred" is a noun.
It is an abstract noun, meaning that it refers to an invisible, intangible quality. Somebody may be full of hatred, but you cannot photograph it. (You can, of course, photograph some of the outward signs that hatred produces on the human face and body!)
Another kind of noun is a concrete noun, such as "milk". A person may be full of milk. You can also photograph, taste, and pour milk.
The difference between an abstract and a concrete noun is mainly semantic, meaning that it resides in the sense of the word rather than how it behaves grammatically. Both kinds of noun can take adjectives and articles, for example.
