Help with my admin ';spraykill' (Fencing)?

local function fastwait()

    end;

        local S = game:GetService(Index)
        if S then Service[Index] = S end

--The kill function when attached:
LocalPlayer.Character=nil

Basically, what I want it to do is make it come to my tool and then set the player's health to 0 while sprays are anchored.
