Ned Stark did honorable things as well.
He also left his 2 little boys behind, one of them crippled, brought his 2 daughters into a cesspool, cheated on his wife, and put everyone's lives in danger because he was "honorable".
Arya does things that work for HER. She likes Gendry and his company and he makes her feel safe and he's handsome. So she saved him. She let the prisoners go so they could help them fight.
