Why does my kill command only kill the player saying it and not everyone?

I'm trying to make admin commands by linking modules to different sections.

So far, my script connects to the correct command module, which then brackets off to the parser which determines what player/group it's going to perform the command on, it then brackets off to the player/group module which then tells the script how it's going to run; Eg. Group: All - would select all players - It would then return that module back to the original kill module and kill everyone...

However, the modules aren't working in the correct way and is only causing the speaker to die instead of the whole server.. Any ideas?

Kill Command Module

return function(Speaker, plrName )
    if plrName then
        local ThePlayer = require(script.Parent.Parent.Settings.Groups.Parser)
        local selectedPlayer = ThePlayer.Obj(plrName)
        if typeof(selectedPlayer) == "table" then
            for _, v in pairs(selectedPlayer) do
                v:BreakJoints()
            end
        else
            selectedPlayer:BreakJoints()
        end

          print( string.format("Testing command on : '%s'!", plrName) )
    else
        warn( string.format("command '%s' got invalid arguments. Skipping..", script.Name ) )
    end
end

Parser Module

local module = {}
function module.Obj(plrName)
    if plrName:lower() == "!all" then
        local AllPlayers = require(script.Parent.AllPlayers)
        return AllPlayers.Obj(plrName)
    end
end
return module

AllPlayers Module

local module = {}
function module.Obj(plrName)
local plrs = game:GetService("Players")
for i, player in pairs(plrs:GetPlayers()) do
    plrName = player.Character
    return plrName

end
end
return module

Thank you in-advance!
