Answer:
Retribution
Step-by-step explanation:
The mother of someone who was murdered publicly recommended a sentence to serve as vindication for her slain child. She continues to note that she believes the offender will never experience remorse for his actions. This type of punishment is called Retribution.
Retribution simply means a "payback punishment" punishment inflicted on an individual for a previous or earlier wrong doing, most times Retribution is done in order to "settle scores" for something wrong a person did to you and are unforgivable.
"Settle score" is the act keeping in mind something bad or unpleasant someone did in order to pay the person back in his own coin (which means doing bad thing in return)
