Is karma a virtue ethics?

Is karma a virtue ethics? I know that some people link the path to virtues such as wisdom or charity, but what about the theory of karma in general? I am asking because I wondered whether unvirtuous actions that are not easily explained in terms of violations of the precepts (e.g.) are bad karma. e.g. the virtue of good will and benevolence is often said to be "wholesome" in intent; I definitely don't think it's for monastics only, but that wholesomeness means good (karma) > In the Pāli Canon, the term metta appears in many texts such as the > Kakacupama Sutta and Karaniya Metta Sutta. Other canonical materials, > such as in the Paṭisambhidāmagga, elaborate on it as a practice. Yet > other canonical sources, such as the Abhidhamma, underline the key > role of benevolence in the development of wholesome karma for better > rebirths likewise, the converse > Greed (lobha) is a root of unwholesome karma; Hatred (dosa) is a root > of unwholesome karma; Delusion (moha) is a root of unwholesome karma There is a difference between non attachment or elimination of the poisons, and not being ruled by them; isn't that difference that of religion and virtue?
