Why did menelaus become angry with Paris?

Menelaus became angry with Paris because Paris abducted Helen, Menelaus's wife, leading to a significant breach of hospitality and honor. This act not only caused personal betrayal but also instigated the Trojan War, as Menelaus sought to reclaim Helen and restore his reputation. His anger was fueled by a sense of injustice and the desire to avenge the dishonor brought upon him and his household.
