It's kind of like prison. Everyone says they're innocent. Some guilty people might even sincerely believe they're innocent. But when everyone is saying they didn't do anything wrong it's really hard for the person who actually didn't do anything wrong to get "justice."

Many spammers don't see how what they are doing is wrong. They run a LinkedIn scraper to collect 100,000 business emails for people in their industry and they want to email them.

Combined, it's enough to convince someone to stop offering humanity and sympathy to those who have acted badly, knowingly or otherwise.
