There are bad people in this world and they do bad things.
They must be corrected.
The correction must be strong enough to make them fear to ever do bad again.
It must also be strong enough to deter other bad people.
If they cannot be corrected, then they must be separated from society permanently or terminated.
Normal people should not have to worry about others who can’t be corrected.
The fundamental problem is that it would be easy to create a secure internet architecture, but the CIA and NSA don't want that because they use security vulnerabilities to spy.
