During the meal at the palace that the beggar/Odysseus attends, Athena inspires the suitors to behave even more poorly than they normally do.

Why would she do this?

Athena inspires the suitors to behave even more poorly that they normally do because she has a vow in which she has the will of protecting the Odysseus from the suitors and in the same time, she cause these problems because she wants to see the patience of Odysseus.
