More than fair enough Jace. I had them pegged as akin to deep sleeper agents, often like those used by the FBI, CIA or other (if you'll permit the pun) alphabet soup agencies. Like any undercover agent, there is a good deal of stress on the man. Perhaps we could assume a lost family on either behalf during the Clone Wars, faulted to the Republic? Or perhaps both are genuinely devoted to the anti-Imperial movement and are willing to take the risks involved. People can be great fakers and hiders of true feelings. It's just a matter of how good you are at masking things. If anything, I'd say they are closed to well-hidden sociopaths than any thing else really.
