Whistleblowing always makes it more difficult for the human rights violators. Some of these people will finish their workday in government or tech companies and be with families and friends who really don't care about their actions, but even then, they still have to wonder and worry.

"Do they think I'm spying on them, after Snowden reported that NSA men passed around private images of girls they found? Will I be named in the history books as a monster?"

It's always worth it. It's karma.
