Could have the hanging be dealt better and been more respectful "yes".
Saddam I believe though was not respectful to His Countrymen when He ruled over them.
Did He get what He deserved yes and no. Remember this how many more did He kill, torture, gas, war against, etc. 10,000, 100,000, 1,000,000.
Yes it would have been better if they would have been respectful.
