Quite the opposite, Heracles often killed other demigods he came across in his travels.
Heracles might have been a son of Zeus, but he evidently did not feel any kinship with the other gods or their respective offspring. His offenses, curiously, were not restricted to mundane matters and mortal beings he often came to blows with fellow demigods, and even had violent encounters with several of the major gods, themselves.
Although he was labeled a hero, Heracles was often unscrupulous during his adventures, sometimes killing people who likely should not have been killed, and frequently being too handsy with women who did not consent to his advances. Heracles, the legendary son of the Mycenaean princess Alcmene and the Greek god Zeus, was a wide-traveling warrior, adventurer, and a general slayer of countless monsters and villains.
