Suppose someone commits a horrible and inhuman action like a murder. The dead one's parents go to the court and ask the judge to do they best to revenge and according to the regulations throw the book at the killer. I was wondering if someone could tell me if in this scenario all the sentences in the list bellow are identical or they are different in meaning:
- Make him get what he deserves.
- Make him pay the cost for his actions.
- Serve him justice.
For me the sentences #2 and #3 mean the same and both are natural, but I'm a bit doubtful about the first case.
