I don't think the Internet - or Computers, for that matter- has realistically made Crime any worse. It's just a different venue.
In some aspect I'd even argue that it's had a positive effect, As with many crimes it leaves an "audit trail" that can be used to put together illegal activities.
Outside ransomware and scams and fraud, There are far more serious crimes, and I think the Internet has helped with some of that. Where 30 years ago a pedophile could kidnap a kid, do god knows what, then murder them and you *might* hear about it on the local news, Now these weirdo's share their disgusting pictures with other weirdo's and law enforcement can act quickly enough to piece together locations before that happens. Meanwhile evening news never covers that unless it goes awry, so they are thankfully usually left with stories where some guy walked through a playground as a shortcut and they have to interview all the parents who say "Oh no doubt in my mind he wanted to kidnap our kids" or they bring on experts to talk about it at length. And the "expert" looks like he might understand the mind of a pedophile all too well, sort of like how news channels sometimes bring on nutritionists who talk about healthy eating and you can't help but notice they need two chairs.
