In Greek mythology why didn't the other gods like Ares?

He was the god of war, and generally unpleasant. He loved violence and bloodshed. However, it's not fair to say that none of the other gods liked him - in some stories, he is one of Aphrodite's many lovers, and he was very close with his sister, Eris. Eris, the goddess of chaos, rode in his war chariot with him, shrieking with delight.
