Using module scripts to run an admin script, but not functioning how it's intended to?

So i'm trying to make commands which use a grouping system but with modules. In one script holds the command - Which connects to the grouping parser after a player argument is parsed - This is then thrown into the corresponding module of which group has been selected. However, after it has reached the player category/group, i'm having trouble on returning the values to the original script for the command to take place.

For example:

Kill/!all

"!all" gets sent to the grouping "Parser" - Which then detects that we're after everyone so it goes to the "AllPlayers" module, collect all players and then... Well that bit I can't work out how to connect back to the original so it kills all players...

The kill command

return function(Speaker, plrName )

if plrName then
local ThePlayer = require(script.Parent.Parent.Settings.Groups.Parser)
  ThePlayer.Obj(plrName)
	plrName:BreakJoints()

  print( string.format("Testing command on : '%s'!", plrName) )
else

  warn( string.format("command '%s' got invalid arguments. Skipping..", script.Name ) )
end
end

The grouping Parser

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

All players module

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

end
end
return module

How do I get the All players module connect back to the original kill command to make "plrName" die...

Thank you in advance!

I found a fix using @vector3_zero's answer - Just adjusted a few key aspects:

Kill Command

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:

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

All players:

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
