Team killing script not working, player supposed to die if they team kill?

I have 4 types of classes in my game Culprit, Officer, Agent, And Innocent.

What I want to happen is if the Officer or Agent kill each other or kill an Innocent they die.

I have the script I am using now but its not worth posting because it honestly so far off and it doesnt work XD

Theoretically you would check if the player is the officer or agent and then once thats done you would wait for someone to be killed and if the officer killed an innocent then his humanoid.Health would go to 0 but if he killed the culprit nothing would happen and same with the agent. I know how it would work in my mind I just dont know how id actually script it.

Hopefully someone can help me out :) Thanks for your time

Heres the script I have, I decided to add it

function newcharacter(bloxxedplayer, character) 
    local humanoid = character:FindFirstChild("Humanoid")
    if  humanoid then
        humanoid.Died:connect(function()
        end)
    end
end

-- Officer and agent no kill good guys
function newcharacter(bloxxedplayer, character)
    local humanoid = character:FindFirstChild("Humanoid")
    if humanoid then
        humanoid.Died:connect(function()

            local tag = humanoid:FindFirstChild("creator")
            if tag and tag.Value and tag.Value.Parent == game.Players then
                if tag.Value ~= culprit and agent and bloxxedplayer ~= culprit then
                    local wrongdoer = tag.Value
                    if wrongdoer.Character and wrongdoer.Character.Parent then
                        local wrongdoerhumanoid = wrongdoer.Character:FindFirstChild("Humanoid")
                        if wrongdoerhumanoid then
                            wrongdoerhumanoid.Health = 0
                        end
                    end
                end
            end 
        end)
    end
end

There you go :)

I was told I should add the whole script so here it is at about line 50 is the script above.
