For

Against
Universal DHR
Innocent
Does not necessarily stop crime
Encourages violent crime

There are many different conditions towards whether death penalty should be held or not.
In my opinion, I'm FOR death penalty only up to certain reasons.
Why?
Death Penalty should only be held when a life is taken away for no sensible reason.
Such as:-
Murder with Intention
Terrorism
Though, it should not be conducted for:-
Drug Trafficking
Killing for Self Defense
Accident
Being Not Mentally Stable

It is unfair for those who are less fortunate and uneducated about the law. Most wouldn't know the effects of drugs trafficking which leads to them doing it.
Self Defense is mandatory, no one wants a murderer to kill them so instead they would attack first.
Accidents are accidents unless there is an intention to it.
For one who is likely mentally insane has rights to live life normally. Even if they kill, they should be punished instead of sent to death penalty.
