Spiteful means doing small cruel things just to hurt somebody. A spiteful remark, purely spiteful, spiteful behaviour.
The smallness and the pointlessness are both part of it: spite gains the person nothing, which is what makes it worse than self-interest. It describes acts and remarks rather than large cruelties. Note spite, the noun; in spite of, which uses the word in a quite different and now purely grammatical way; and cut off your nose to spite your face.
