was justice done in saddam husseins case???

i personally feel tht hanging saddam was not a fine ending or punishment given to him. well if he had to be punished for proving gilty of killig the shias then killing him in turn is in no way justified as he wouldnt hav understood wht is the importance of life well killing any no of ppl would ultimately kill a person so it sends out a wrong opinion. i feel it would hav been better if he wasnt hanged but was taught anfd shown how precious life is !!
