Don't know about intellegence agencies but I got to know pentesters / red teamers at some large companiese, and they were cool but had a very unsavory side. Several times I found myself in conversations where they were admiting to serious crimes and unethical behavior. I suspect that you need to be passionate about wanting to do bad things if you want to be good at security.
