You don't get protected from the effects of Slave Mentality by taking more disadvantages.

Sense of Duty and/or Reprogramable doesn't stop people from casually walking up to you and telling you to clean their shoes with your tongue. The best you can get is when someone abuses your Slave Mentality to order you to do something that contradicts Reprogrammable or SoD is being forced to do it, and feeling terrible about it afterwards (like if you have a conflict between a SoD and a Vow - one way or another you don't get CP for the session, and you feel bad).

If that doesn't fit how you envision the net effect to be, then it's not that combination of traits.
