Stealing is wrong, of course, but your enemies didn't really need all that stuff, anyway. The thief is there to lighten their load.
Official site's description.
The Thief is a job in Bravely Default, gained by defeating the Jackal at the Harena Ruins.
Thief is the compulsory job to have if one favors to 'collect' rather than shop. The Thief is a fast physical melee job that excels in Agility and Dexterity, as well as using Daggers and Bows. Using Thieves are great against bosses as bosses tends to yield rare items. Simply stealing or mugging them is an awesome way to go, especially for 'collectors'. It's also capable of stealing HP and executing a powerful speed focused attack call Godspeed strike. Its skillset is Thievery.

Edea's jacket has long sleeves worn with her hood up and she wears long brown cargo pants. Agnès's jacket has short sleeves and she wears a short brown skirt and a black headband.
Tiz and Ringabel wear long tan pants with orange belt with tan satchels on the side, brown boots, green fringed scarves, and thin red and green bands on their upper arms. Tiz wears a grey hooded vest and red and green bands around their upper arms, along with tan cargo pants and braided brown belts around their waists. Ringabel wears a long-sleeved blue jacket and black armlets.
