How would I give only one player a StarterCharacter instead of giving it to all players?

I made a script where if you touch a part, you get 4 points. If you have 4 points, then "StarterCharacter" from ReplicatedStorage moves into StarterPlayer, and you die. When you respawn, you look like the StarterCharacter, but so does everyone else when they die.

Here is a script that checks when you join the game whether you have 4 points and creates a leaderboard:

local DSS = game:GetService("DataStoreService")
local PES = DSS:GetDataStore("PlayerExperience")
local RS = game:GetService("ReplicatedStorage")

game.Players.PlayerAdded:Connect(function(plr)
    local char = plr.CharacterAdded:Connect(function(char)
        local charnum = Instance.new("Model",plr)
        charnum.Name = "leaderstats"
        local value = Instance.new("IntValue",charnum)
        value.Name = "Char"


        repeat wait(.1) until char
        if value.Value == 4 then
            if RS:FindFirstChild("StarterCharacter") ~= nil then
                char:BreakJoints()
                RS:FindFirstChild("StarterCharacter").Parent = game.StarterPlayer
            end
        end

    end)



end)

How would I make it so that only the person that touch the part gets the StarterCharacter? A bit like in Jailbreak where if you choose to be a cop, then you are a cop, it doesn't make everyone else a cop as well.

In case you need the script that's inside the part you touch, here it is:

function onTouch(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        local plr = workspace[hit.Parent.Name]
        local player = game.Players:GetPlayerFromCharacter(plr)
        local a = true
        local char = hit.Parent
        if player:WaitForChild("leaderstats"):WaitForChild("Char").Value ~= 4 then
            game:GetService("ReplicatedStorage").StarterCharacter.Parent = game.StarterPlayer
            char.Humanoid.Health = 0
            player:WaitForChild("leaderstats"):WaitForChild("Char").Value = 4
            wait()
            a = false
        end
    end 
end

script.Parent.Touched:Connect(onTouch)
