The module function doesn't return and let it continue instead

[FrizTren (TotallyFriz)]

I’m doing some of module practice, OOP, and something more. I wanted to keep the code simpler as much as I can. I’m curious why another module script doesn’t do the same as the main module script.

Module script

local Utility = {}

function Utility.isFound(object:Instance,DEBUG_MESSAGE:string)
	if object then
		return warn(DEBUG_MESSAGE)
	end
end

return Utility

Another module (Specific line of code)

local MainUtility = require(game.ReplicatedStorage.Modules.MainUtility)

function Character:Clone(name)

	-- this doesn't return
	MainUtility.isFound(script.Parent:FindFirstChild(name),`is found {script.Parent:FindFirstChild(name)}`)

	-- this does return
	if script.Parent:FindFirstChild(name) then return warn(`is found {script.Parent:FindFirstChild(name)}`) end	


	local c = script.Parent.cloneFolder:Clone()
	c.Name = name
	c.Parent = script.Parent
	Character:Preparing(c)
end

And the problem is that the “doesn’t return” one keep cloning folders. (I use while loop just to check if the method is called and found specific folder, then it should return and stop cloning more folders.)

Nevermind, I know another way of doing this.

local folderFound : boolean = MainUtility.isFound(script.Parent:FindFirstChild(name))
	
if folderFound then 
	return
end
