Conscience blocks as in ego, super-ego, super-id, id?
Well, that's actually a very interesting thought. For example, your domineering, forceful ILE can't actually exist, as ILEs/ENTps have "Role Se"; in other words, due to their pursuit of "potential" and abstract stuff (base Ne), they naturally do not pursue material "stuff" or any sort of leverage for exerting their willpower over others (Se).
It's not just limited to ego/super-ego. You're similarly unlikely to find a domineering, forceful SEI (or SLI, for that matter), because Ignoring Se implies avoiding exerting your willpower to get people to do things, which is antithetical to coaxing them to do something with some sort of personally satisfying reward.
