Bodyvelocity knockback happens twice, and not once, why?

I put the knockback coding into a touched event that has also a damage script in as well. The knockback works well and fine, but it knockbacks the dummy twice and not once. Any reasons why this is happening?

for i = 1,7 do
		wait(.033)
		gomuWeld.C1 = gomuWeld.C1 * CFrame.new(0.01, 0.1, 0)
		gomuArm.Touched:Connect(function(hits)
			if hits == nil then return end
			if hits.Parent.Name == player.Name then return end
			if hits.Parent:FindFirstChild("Humanoid") then
				if hits.Parent:FindFirstChild("Pistol") == nil then
					local debounce = Instance.new("BoolValue")
					debounce.Parent = hits.Parent
					debounce.Name = "Pistol"
				if hits.Parent.Pistol.Value == false then
					hits.Parent:FindFirstChild("Humanoid"):TakeDamage(30)
					hits.Parent.Pistol.Value = true
					wait(1)
					if hits.Parent == nil then return end
					hits.Parent.Pistol:Destroy()
				end
				end	
				local KnockBack = Instance.new("BodyVelocity")
				KnockBack.Parent = hits.Parent:FindFirstChild("HumanoidRootPart")
				KnockBack.MaxForce = Vector3.new(80000,80000,80000)
				KnockBack.Velocity = character:FindFirstChild("HumanoidRootPart").CFrame.LookVector * 50 -- based on the direction YOUR character is facing.
				game.Debris:AddItem(KnockBack, 0.1)
			end
		end)
