Based on previous knowledge of greek values, what prediction can best be made about antinous’s future?

The correct answer is :

Antinous's friends will turn on him, and he will suffer for his actions.

In Homer´s Odyssey, Antinous attacks a beggar, who is really Odysseus. Even the other suitors disapprove of it because it was a disregard for the practice of Xenia, meaning the guest-friend hospitality.  

Later, Antinous would be the first of the suitors to be killed by Odysseus.
