Definitly a tricky one right there, had to roll up my sleeves to break it down.
First of all, Nas spits “hell is men” and it is actually the second part of a short anaphora started with “like” two bars ealier.
This being said he asserts being “like (..) wolves in the night” because “hell is men”, which is by the way Nas’s own translation of famous saying of French former pulitzer-prize awarded Jean-paul Sartre. The original saying, “L'enfer, c'est les autres”, is usually referred to as “Hell is other people”
For the record Sartre used it in one of his most sucessfull play, “huis-clos”/“no exit” (1944). An afterlife tale which deals with the fate of three individuals sent to hell after their deaths. Hell is nothing else than a tiny room in which the damned souls are condemn to stay forever. Soon, they realize their sentence is actually much more dreadful than they thought in the first place because they can’t get along together. One of em lets the words out: “l'enfer, c'est les autres”
