It is a rule that if you want to receive a service from society, you must appreciate that it is a good service and you must be ready to do it yourself. Sometimes you may not be good at it. So you can let someone else do it.
For example, a doctor treates you. You want his service. So you must appreciate it is a good service. So you must be ready to be a doctor. But some of you do not have the skill to be a doctor. So you need not be a doctor.
Now comes the job of an executioner. If you think some criminals are to be hanged, you must be ready to do it by yourself. Here you can't say you don't have the skill to do it. It is very easy to hang a man. Can you do it? If you can't do it, don't advocate for it. Please do not say that you are a respected lady or a gentleman hence some hangman must do that job for you.
So whatever may the case. Let it be a murder of a rape. Do not advocate for death sentences if you can't do it by yourself.
Personally, I can't kill a man. So I say "Capital Punishment should be abolished".
