Why do you think Antonius treats Odysseus so bad?

Antonius treats Odysseus poorly primarily due to his pride and desire for power. As a suitor vying for Penelope's hand, he views Odysseus as a rival and a threat to his ambitions. Additionally, he underestimates Odysseus, seeing him as a beggar rather than the cunning hero he truly is, which fuels his disdain. This contempt is further amplified by the suitors' general arrogance and entitlement in Odysseus's absence.
