You're right in that you shouldn't use your skills for unethical activity. However, since you mentioned you're an attorney I'm wondering if an official professional code of conduct does really help with that. There are plenty of lawyers engaging in unethical behaviour and the Bar often doesn't bar them from doing so.
Case in point: The way Aaron Schwartz was treated. The prosecution seriously overstepped the boundaries of what can be considered ethical behaviour. Even worse, they did it for shady political reasons and personal career considerations.
