I believe that, some criminals are simply dangerous for the society and will always be no matter how much opportunities and support they are given, and they should be given the death penalty. But if there is a slightest chance that the criminal was a victim of the situation and tried to save his/herself or any logic in favour of the crime, should be given chance at least once. And the capital punishment should be used only in some extreme cases rather than using it as the law prevailing policy.
