When Odysseus Comes Home and kills his own people to get his wife back

Today I got to witness when Odysseus came home to Ithaca when he was unrecognizable because he was dressed as a beggar so he could draw his bow and win his wife back fairly because he has been gone for so long. Then he drew the bow and shot someone square in the neck and told everyone he was The Great Odysseus and he would kill them all because they were all trying to take his place as king.  His son, Telemachus found out it really was his father and he helped with the gods kill everyone that was trying to take his place. When he saw Penelope, his beloved wife she didn't believe it was really him until he pointed out that someone had moved their bed, which was irremovable because it was carved into the roots of a olive tree. Then she knew it was him.
