spectate doesn't loop at death?

When a player dies whilst being spectated the person spectating has to loop back to the player. Is their anyway to make the script so that it works even if the player being spectated dies

cam = game.Workspace.CurrentCamera

local bar = script.Parent.Bar
local title = bar.Title
local prev = bar.Previous
local nex = bar.Next
local button = script.Parent.Button

function get()
    for _,v in pairs(game.Players:GetPlayers())do
        if v.Name == title.Text then
            return(_)
        end
    end
end


local debounce = false
button.MouseButton1Click:connect(function()
    if debounce == false then debounce = true
        bar:TweenPosition(UDim2.new(.5,-100,0.88,-50),"In","Linear",1,true)
        pcall(function()
                title.Text = game.Players:GetPlayerFromCharacter(cam.CameraSubject.Parent).Name
        end)
    elseif debounce == true then debounce = false
        pcall(function() cam.CameraSubject = game.Players.LocalPlayer.Character.Humanoid end)
            bar:TweenPosition(UDim2.new(-1,-100,0.88,-50),"In","Linear",1,true)
        end
end)

prev.MouseButton1Click:connect(function()
    wait(.1)
    local players = game.Players:GetPlayers()
    local num = get()
    if not pcall(function() 
        cam.CameraSubject = players[num-1].Character.Humanoid
        end) then
        cam.CameraSubject = players[#players].Character.Humanoid
    end
pcall(function()
                title.Text = game.Players:GetPlayerFromCharacter(cam.CameraSubject.Parent).Name
        end)
end)

nex.MouseButton1Click:connect(function()
    wait(.1)
    local players = game.Players:GetPlayers()
    local num = get()
    if not pcall(function() 
        cam.CameraSubject = players[num+1].Character.Humanoid
        end) then
        cam.CameraSubject = players[1].Character.Humanoid
    end
pcall(function()
                title.Text = game.Players:GetPlayerFromCharacter(cam.CameraSubject.Parent).Name
        end)
end)
