(A) Sly charges me with attempted murder. Sly does not think that his counterpart in the other Everett branch is not interacting with him—actually, Sly, after reading LW a lot, thinks that he has a “causal” responsibility, going-back-in-time, on whether his counterpart lives in the other branch, and therefore on how well the other branch fares. (If we transform this grenade into a counterfactual mugging grenade that has an option to not be “probably lethal” conditional on Sly’s refusing of $100, Sly has causal effect on whether he lives in the other branch. With a lethal-only quantum grenade, Sly is left with responsibility to consistently ban uses of the grenade, so he should refuse $100 and put charges anyway—producing of such grenades is “sick”.)
