Odysseus went to war for ten years in Athens, He then had to sail back home from said war after he had won. It took Odysseus another ten years to get back home, through his twenty years away his wife was loyal to him and was waiting for him to return. Odysseus, Loyal? AHAHAHA. Anyways Odysseus could technically be called a hero by saving his crew from Polyphemus the cyclops, from the sirens and sea monsters to the oracle. He is most definitely flawed, he cheated multiple times, let good men die, etc
