Why do you think punishment for serious crime is revenge?The legal system shouldn't be driven by emotion, or revenge. That's not what it's supposed to be about.
People who think the law is a tool for getting revenge are dangerous indeed.
As to the payout, in the US you can sue for punitive damages that can consider personal wealth. This is in general a good thing, so someone on the poverty line will get a much small fine than a millionaire. But then things get blurry because the claims are made with the knowledge they will always be negotiated downwards so you start at a high level. But if the defendent does publicaly reveal their welath then the jury wont know how much can be punished, If Giuliani is really worth about 50mil, then the goal would be dmaages of say 45-47mil to strip him of nost of his wealth so he is actaully punished, rather than a 100K fine which is probably 1 weeks interest payments
