It's only deep if you want it to be deep. In my opinion, it's as "deep" as any other meaningless question. As one in the title, by the way. Because the very assumption that legal system exists to help some commoner — you — seems absurd to me. It's not you who puts people in jail. It's not you who has the guns and manpower to maintain the existing regime and rules. It's not even you, who "feeds" those who have guns and manpower — regardless of what you think, you don't really chose to pay taxes, you just have to, because if you don't, then you are the "criminal" who must be punished.
These questions seem deep (which actually translates to "without an obvious answer") only if you assume that you are choosing who should be punished, what is a crime and what is a punishment. Then, unsurprisingly, it is quite hard to explain rationally the current state of things — so that "your" choices would seem "right" enough. Because that's just not the case.
But if you try to answer the question about "what is right" from the "Golem's" point of view — the legal system, the government, the "social norm" — it actually is pretty clear and simple. "Right" is what keeps it stable. Punishing somebody, who makes somebody else miserable doesn't really help it — it's ok for people to be miserable, it's not ok for them to turn on the Golem. It doesn't have to be rational or efficient, it doesn't have to help anybody or protect anybody. The moment it becomes something more than a mere human — and it long time is — it doesn't care for human needs or worries. Feeding murderers on behalf of other people, while keeping them in a closed institution doesn't really help anybody or is rational, it isn't about justice or whatever — it just works, it just keeps the system stable. On the other hand, people using psychedelic drugs and living in hippie communes doesn't hurt people, but hurts the system. That's why things are what they are.
