I'm not very fond of the D&D alignment system, or that test, even within the confines thereof. To work at all, it should minimally be sliding scales rather than simple categorization, but given that there's game rules that explicitly rely on those categories to function, oh well.
If you put a gun to my head, I'd say Ze'ev is probably neutral or neutral good. While he's philosophically in explicit favor of the rule of the law qua the law, he's proven perfectly willing to break it when it benefits him, not just with the illegal boosters but bribery, false identities, and fraudulent business transactions. And while he commits a fair bit of time and money to altruistic causes, it's not clear to me that he has sufficient commitment to them in and of themselves to qualify as "D&D Good." He's never really sacrificed for them, he just throws money (acquired through business transactions that ultimately, inevitably feed into the cycle of capsuleer violence) at them.
