From the one law class I took in college, civil courts are for one person to get reputations from another. Criminal courts are for society to get respirations from a person. A criminal fine is about paying back society because your lack of following the law is making people around you feel unsafe.

The victim of your crime can sue you independently and get additional money from you. I believe they can even use the evidence from the criminal trial and a civil trial is much easier to win.
