Characters with this defect are prone to taking things that don't belong to them. In some cases it's a form of addiction, where they enjoy the adrenaline rush of stealing, and they can't stop. In other cases, it's a compulsion that they feel like they have to do, and they wish they could stop. Others with the condition may not even be aware that they're stealing; they either block it out mentally, or are clueless to the fact that other people's property is not theirs for the taking. This defect might also lead to hoarding behavior, as the character winds up with more property than they know what to do with.
Remember, this is a defect, meaning that it goes beyond the point of normal behavior (all PCs loot defeated villains' things) and into the realm of nuisance: It must present some hardship to the character. They get in trouble sometimes for stealing, or they antagonize allies, or they get distracted stealing things when they should pay attention or defend themselves, et cetera. Whether or not items belonging to fellow PCs get taken is up to the player and the level of the defect.
Level One: The character is somewhat in control of the kleptomania, and avoids taking very valuable or conspicuous or dangerous things that would get him or her in trouble.
Level Two: The character is out of control, and must steal even when it would get them into a lot of trouble.
