As the goddess of peace (I am actually Devesh but that is irrelevant), I believe that conflicts should always tried to be solved peacefully.

Athena is not following this principle, she is constantly trying to create unnecessary violence between the suitors and Odysseus/Telemachus.

So why should you, a child (or teacher) who lives 6000 miles away from Greece, sign? Well I hope my very casual and easy-to-read evidence convinces you: 

After the suitor Amphinomus treats the beggar-disguised Odysseus nicely, the beggar-disguised Odysseus warns Amphinomus to leave before Odysseus returns, and Amphinomus then became “sick with anguish … / [and] fraught with grave forebodings … / [B]ut not even so could he escape his fate. / Even then Athena bound him fast to death…” (18.176-179). Even though Amphinomus was a generally kind and moral suitor, Athena still makes him die instead of letting him leave and having the conflict resolve more peacefully. Immediately afterwards, “Athena … / inspired Penelope … / to display herself to her suitors, fan their hearts, / inflame them more…” (18.181-184). Athena is trying to make the suitors long more for Penelope which will make the suitors want to fight harder to win Penelope over. Athena should be trying to drive the suitors away from Penelope so a fight does not occur. Later, when Melantho, a maid of Penelope, gets into an argument with the beggar-disguised Odysseus, the suitors start insulting Odysseus as “Athena had no mind to let the brazen suitors / hold back now from their heart-rending insults— / she meant to make the anguish cut still deeper / into the core of … Odysseus” (18.391-394). Athena is provoking Odysseus to fight by making the suitors seem harsher than they actually are. 

Athena should stop trying to interfere with the mortals' lives. If she continues doing this, it will lead to unnecessary bloodshed.
