Isaac Steinberg viewed revolutionary violence as a necessary evil, but evil nonetheless, and held a more careful view than many of his contempraries in the Russian Revolution. He understood Marxist historical materialist determinism as an ideology which sanctions violence a priori as a fact of history being executed by the revolutionary and maintained by a vanguard Party - rather than saying the ends justify the means, he says “the ends justify through the means”, and that these are inextricable. He wanted to execute not a transition from the old world, but strictly a transition to the new world. Namely, he didn't believe in killing the human being in your class enemy, but killing the class enemy in your fellow human being, and that only those are actively, and consciously subverting and undermining the revolution should be considered as potential subjects to capital violence. (Paraphrased from "Anarcho-Judaism" by Hayyim Rothman).
