The answer to this question is no,I don't believe in capital punishment..
I don't accept when someones life is being taken because of a crime he committed.
There are other punishment that can be use for crime without the needs to kill the person irrespective of the crime committed.
There are many countries that practice capital punishment especially countries in Asia, middle East and USA..
The highest crime someone can commit is murder that is to take someones life,and I think in my own view that such person should be sentenced to life imprisonment with hard labor, let him pay for his crime there in prison than for him to be sentenced to death.
But in countries like China, Thailand, Saudi Arabia, Vietnam and other Asia countries, drug trafficking, rapes, blasphemy, stealing are punishable by death.
My conclusion is,human being does not have the right to take someones life no matter what, even the government does not have the right to end someones life only God.
There are other punishment that can substitute for capital punishment.
