Tool Animation Playing when unequipped?

I have this idle animation equipped in a tool, which plays the idle when equipped, then if I press W stops and when I release W plays again. But when I am pressing W and unequip the tool at the same time the animation keeps playing. I've tried adding some stuff but nothing is working so I turned to this

local player = game.Players.LocalPlayer

repeat wait(1) until player.Character

local character = player.Character
local humanoid = character:WaitForChild("Humanoid")

local userInput = game:GetService("UserInputService")

local animation = Instance.new("Animation")
animation.Name = "Idle"
animation.Parent = script.Parent

local animation2 = Instance.new("Animation")
animation2.Name = "Equip"
animation2.Parent = script.Parent


animation.AnimationId = "rbxassetid://5188207897"  
local animtrack = humanoid:LoadAnimation(animation)

animation2.AnimationId = "rbxassetid://5188248725"  --5188248725
local animtrack2 = humanoid:LoadAnimation(animation2)
animtrack2.Priority = Enum.AnimationPriority.Action
local tool = script.Parent

script.Parent.Equipped:connect(function()
    animtrack2:Play()
    script.Parent.Sound:Play()
end)
wait(.26)
script.Parent.Equipped:connect(function()
    animtrack:Play()

    userInput.InputBegan:Connect(function(input)

         if input.KeyCode == Enum.KeyCode.W  then

        animtrack:Stop()
    end
end)

userInput.InputEnded:Connect(function(input)    
         if input.KeyCode == Enum.KeyCode.W then
            animtrack:Play()
        elseif tool.Unequipped == true and input.KeyCode == Enum.KeyCode.W then
            animtrack:Stop()

    end
end)



end)

script.Parent.Unequipped:connect(function()
    animtrack:Stop()

    userInput.InputEnded:Connect(function(input)    
         if input.KeyCode == Enum.KeyCode.W then

            animtrack:Stop()
        end
        end)
end)
