they were pissed off so they decided to kill Odysseus (they still thought he was a beggar) and he and his mates wasted them all
The suitors considered Antinous ungracious for treating the beggar so poorly and warned Antinous that if the beggar were really a god, then Antinous might suffer some ill fate.
The other suitors do not think it right that Antinous has assaulted Odysseus (the beggar), and warn that it may be some god in disguise. After realizing that Odysseus has killed Antinous intentionally and intends to kill them all, they try to appease Odysseus by blaming all the trouble on Antinous.
After Antinous is killed, the other suitors look for their weapons so that they can kill Odysseus in revenge. They can find neither shield nor spear.
Of the suitors, Odysseus first kill Antinous with an arrow to the throat. He then kills Eurymachus with an arrow to his liver, before killing many other suitors.
Antinous, one of the suitors, was the one who spoke out against Odysseus to the other suitors and wanted to kill him. He was the ringleader among the wooers.
Eurymachus blamed the behavior of the suitors on Antinous, as he portrayed him as the main instigator of their misdeeds against Odysseus. Eurymachus tried to shift the blame away from himself and the other suitors by placing it primarily on Antinous.
In Homer's Odyssey, there is no evidence to suggest that Antinous loves Penelope. Antinous and the other suitors are primarily interested in marrying Penelope to gain control of Odysseus's wealth and kingdom. Their intentions are selfish and driven by greed rather than genuine love.

The suitors encouraged the two to fight. They began wagering on the outcome, and shouted at the participants to beat each other down. They also swore not to give Odysseus a dirty blow while they were fighting. Antinous threatened Irus should he lose.
In Homer's "The Odyssey," the suitor who acts as a bully towards Odysseus when he returns home is Antinous. Antinous is one of the leading suitors competing for Penelope's hand in marriage while Odysseus is away. He is depicted as arrogant, disrespectful, and cruel towards Odysseus and Telemachus.
Odysseus accuses Antinous of having looks better than his breeding. He calls him stingy with other people's (Telemachus') food.
Antinous has always been rich. He is incredibly arrogant, and thinks that his social stature makes him better than others. Antinous looks down upon the poor as if they have some sort of contagious disease. Any attacks on his standing or character are taken poorly. When Odysseus, the beggar, criticizes him, Antinous does not take it well. It is possible that he may be compensating for his inadequacies in other areas such as fighting.
