How can I prevent the sword from getting more kills?

I am making a sword that has a killstreak feature, each time you get a kill, the Intvalue called "Kills" value change by 1 but It appears to get a extra 3 kills, wondering why

Script (Server):

local Tool = script.Parent
local SoundFolder = Tool.Sounds
local SlashAttack
local Boolens = {
    Debounce = false,
    CanDamage = false
}
local Animations = { ---Oh boi there Is alot
    EquipAnimation = Tool.EquipAnimation,
    Idle = Tool.Idle,
    Slash = Tool.Slash,
}

Tool.Equipped:Connect(function()
    SoundFolder.Unsheath:Play()
    local Humanoid = Tool.Parent.Humanoid

    local EquipAnimationTrack = Humanoid:FindFirstChild("Animator"):LoadAnimation(Animations.EquipAnimation)
    EquipAnimationTrack:Play()
    task.wait(0.30)
    local Idle = Humanoid:FindFirstChild("Animator"):LoadAnimation(Animations.Idle)
    Idle:Play()
    Tool.Unequipped:Connect(function()
        Idle:Stop()
    end)
end)

Tool.Activated:Connect(function()
    if not Boolens.Debounce then
        Boolens.Debounce = true
        Boolens.CanDamage = true
        SoundFolder.Slash:Play()
        print("The tool has been clicked")
        local Humanoid = Tool.Parent.Humanoid

        SlashAttack = Humanoid:FindFirstChild("Animator"):LoadAnimation(Animations.Slash)
        SlashAttack:Play()
        task.wait(0.5)
        Boolens.CanDamage = false
        wait(1)
        Boolens.Debounce = false
    end
end)

Tool.Handle.Touched:Connect(function(hit)
    local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
    if Player then
        local player1 = game.Players:GetPlayerFromCharacter(Tool.Parent)
        local player2 = game.Players:GetPlayerFromCharacter(hit.Parent)

        if (player1 ~= nil) and (player2 ~= nil) then
            local humanoid = (player2.Character or player2.CharacterAdded:Wait()):FindFirstChildWhichIsA("Humanoid")

            if (player1.TeamColor ~= player2.TeamColor) then
                if (humanoid ~= nil) and Boolens.CanDamage == true then
                    Boolens.CanDamage = false
                    humanoid:TakeDamage(30)
                    humanoid.WalkSpeed = 10
                    humanoid.JumpPower = 30
                    wait(5)
                    humanoid.WalkSpeed = 16
                    humanoid.JumpPower = 50
                    if humanoid.Health == 0 then
                        SoundFolder["Kill Get"]:Play()
                        Tool.Kills.Value = Tool.Kills.Value + 1
                    end
                end
            end
        end
    else
        local NPCHumanoid = hit.Parent:WaitForChild("Humanoid")
        if NPCHumanoid and Boolens.CanDamage == true then
            Boolens.CanDamage = false
            NPCHumanoid:TakeDamage(30)
            NPCHumanoid.WalkSpeed = 10
            NPCHumanoid.JumpPower = 30
            wait(5)
            NPCHumanoid.WalkSpeed = 16
            NPCHumanoid.JumpPower = 50
            if NPCHumanoid.Health == 0 then
                SoundFolder["Kill Get"]:Play()
                Tool.Kills.Value = Tool.Kills.Value + 1
            end
        end
    end
end)
