The important thing to remember about the Wolf Burglar is that, while what he did benefited the poor and downtrodden in Kugane, doing so wasn't his goal. His only aim was to get the Soboro Sukehiro; helping the poor was just a consequence of him not caring about the rest of the things he stole. Therefore calling him "Kugane's Robin Hood" reflects how the citizenry sees him, but it's not entirely accurate to who he really is. (Chaotic Good vs. Chaotic Neutral)
