Or HaChaim
You will note that the Torah (or the brothers) describes all the people of having "defiled their sister" (34,26). This shows that they all shared equally in the guilt of kidnapping. The reason the Torah does not speak about these people having "stolen" their sister is that the principal sin they were guilty of was that it was the kind of robbery which could not be made good. [If you kidnap a virgin and you give back a woman who has been defiled by sexual intercourse out of wedlock this is not a proper restoration. Ed.] The Torah makes it plain by using the term "they had defiled," that if the sin had not been one that could not be reversed the brothers would not have killed all the males in the town. While it is certainly true that the people of Shechem were not the only ones in the world guilty of such crimes, and Noachides who have committed robbery are all guilty of the death penalty, the brothers could certainly not be expected to play executioners in all such instances. They lacked the power to do so. Jacob himself alluded to this when he accused Shimon and Levi as "distressing" him, especially in view of the fact that his family was "numerically weak" (verse 30).
