There is no answer, why were any of the gods deities?
Best I can find, there is no Cupid outside of Roman Mythology, where Cupid (the deity's real name) is the son of Venus and Mars.
Cupid is the son of the Roman deity Venus. Cupid's Greek equivalent Eros is the son of Venus's Greek equivalent Aphrodite.
Cupid is the Roman god of erotic love (also known as Amor) his area of control is love and courtship. In Greece the equivalent deity is Eros.A god.
The love Deity is, of course, the God of Abraham, Isaac and Jacob. However, I'll assume you meant to ask about the mythological deities. The Roman love god was Cupid, and the Greek love god was Eros.
Aphrodite and Ares gave birth to Eros. Eros means Love in Greek. He was the god of sexual love and beauty. He was also worshipped as a fertility deity. His Roman counterpart was Cupid meaning "desire" also known as Amor ("love").
Cupid - Cupid album - was created in 2001.
