Would you support your husband "ruining" a family over something that happened 17 years ago

17 years ago my husband was sexually abused by his private tutor. He was home schooled so his parents hired the guy to help him and he sexually abused my husband for YEARS. It started when my husband was 12 and continued until my husband was 16. My husband opened up about it in marriage counseling and we found out the statute of limitation in our state is different for minors. If it happened when you were a minor you have until you're 45 to report it. So my husband has decided to try and pursue charges. I completely support him but a lot of people, his own family included want me to talk my husband out of it because it happened so long ago and the guy has a wife and kids now. I don't think that matters. He was a grown adult sexually abusing a child and who knows how many other children he could have done that to. I want to support my husband. Would you talk your husband out of it just because the guy has a family? I think my husband needs my support.
