Why does only the first command get read in the table?

local admin = game:GetService("ReplicatedStorage"):WaitForChild("AdminEvent")
local adminPanel = game.ServerStorage.ServerData.Other.AdminGui
local cmdlist = {"kick","god","kill"}


game.Players.PlayerAdded:Connect(function(plr) -- Add admin UI
    if plr:GetRankInGroup(3957601) >= 252 then
        local addpanel = adminPanel:Clone()
        repeat wait() until plr:HasAppearanceLoaded()
        addpanel.Parent = plr.PlayerGui
    end
end)
admin.OnServerEvent:Connect(function(plr, cmd, par1, par2) -- On command event run
    if plr:GetRankInGroup(3957601) >= 252 then
        local function check() -- check if cmd is an actual command
            for i,v in pairs(cmdlist) do
                if v == cmd then
                    return true -- if yes, return true
                else
                    return nil -- if not, return nothing
                end
            end        
        end

        if check() then -- if check() returns true, check for parameters
            if par1 ~= "" or par2 ~= "" then    -- if parameters arent nil then run command    
                print(plr.Name.." ran command: '"..cmd.." "..par1.." "..par2.."'") -- print command ran to output

    -- Commands --

    if cmd == "kick" then
        if par2 ~= "" or par2 ~= "[Parameter2]" then
        game.Players[par1]:Kick(par2)
        else
        game.Players[par1]:Kick()
        end
    end

    if cmd == "kill" then
        workspace[par1].Humanoid.Health = 0
    end

    if cmd == "god" then
        if workspace[par1].Humanoid.MaxHealth == 100 then
            workspace[par1].Humanoid.MaxHealth = math.huge
        else
            workspace[par1].Humanoid.MaxHealth = 100
        end
    end        

            else
                print("Error: No parameters!") -- Error if no parameters are given
            end
        else
            print("Error: Invalid command") -- Error if command is invalid
        end

    else
        plr:Kick("Error: User is not admin! (Reason: DONT EXPLOIT AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!)") -- If the player isn't admin, kick him for exploitation
    end
end)

Basically if i input the params for "kick" it works just fine, and I suspect its because its first in the table, however any other commands, aka god or kill just prints "Invalid Command". I know that the problem lies somewhere in the table, however I have no clue how to solve this issue, I'd be grateful to get an explanation.
