This sentiment would only apply to fictional people in fairytales. I.e. criminals break laws because they are themselves bad and good honest people would never require being imprisoned in the first place. In this hypothetical good/evil then maximum punishment for the evil makes sense. The problem is that real people are more complex than that and so the punishment you are proposing is not proportional to the crimes committed. I know its easier to not have to consider all the variables in every case and just proclaim “to hell with them all!” and call it a day but I hope that we are all not so desperate that we can’t take the time to think about the issues and make a balanced (but more complex) opinion.
