Script no longer run after humanoid's death?

So, I'm making a combat system with various attacks/functions but I just discovered that the attacks no longer run after the humanoid has been killed. What might be the case here?

If you're curious about the scripts;

Local Script under StarterPack:

local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(input, gameProcessed)
    if input.KeyCode == Enum.KeyCode.Q then
        game.ReplicatedStorage.RemoteLP:FireServer()        
    end

    if input.KeyCode == Enum.KeyCode.E then
        game.ReplicatedStorage.RemoteRP:FireServer()        
    end

    if input.KeyCode == Enum.KeyCode.Z then
        game.ReplicatedStorage.RemoteLK:FireServer()        
    end

    if input.KeyCode == Enum.KeyCode.C then
        game.ReplicatedStorage.RemoteRK:FireServer()        
    end 
end)

Server Script under ServerScriptStorage:

game.Players.PlayerAdded:Connect(function(player)
    local player = player
    local character = player.Character or player.CharacterAdded:Wait()
    local humanoid = character:WaitForChild("Humanoid")

    local debounce = false

    local leftPunching = false
    local rightPunching = false
    local leftKicking = false
    local rightKicking = false

    local LPcooldown = false
    local RPcooldown = false 
    local LKcooldown = false
    local RKcooldown = false

    local function leftPunch()
        local leftPunch = script.LeftPunch
        local leftPunchTrack = humanoid:LoadAnimation(leftPunch)
        local leftFist = character:WaitForChild("Left Arm")

        if not LPcooldown then
            LPcooldown = true

            leftPunching = true

            leftPunchTrack:Play()

            wait(1)

            LPcooldown = false

            leftPunching = false
        end 

        leftFist.Touched:Connect(function(hit)
            local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")

            if humanoid and leftPunching then
                if not debounce then
                    debounce = true

                    humanoid:TakeDamage(10)

                    wait(.5)
                    debounce = false
                end
            end
        end)
    end

    local function rightPunch()
        local rightPunch = script.RightPunch
        local rightPunchTrack = humanoid:LoadAnimation(rightPunch)
        local rightFist = character:WaitForChild("Right Arm")

        if not RPcooldown then
            RPcooldown = true   

            rightPunching = true

            rightPunchTrack:Play()  

            wait(1)
