I appretiate your responses already. Thank you all.
If you're playing a character who feels strongly enough that an oath sworn should be kept, and will also not swear an oath that they intend to break, even though refusing this will negate their actual goals, in order to keep to that, then you are really playing a more lawful character than anything else; lawful doesn't necessarily mean following social legal codes, it just means putting codes of conduct or principle ahead of your personal views on right action if the two conflict.
I guess it's a matter of wording and intepretation. In this case, I did bring the "principle" argument. When I was playing I was mostly thinking "don't blackmail me and tell me what to do" (but also, I don't want to aggravate the situation) x) I do find it hard to put my thoughts on this situation. Hence this post :p
Usually, I'm more one to follow my conscience but also put a lot of value on freedom. But in this case there was no option that clicked with me.
It's pretty 50-50 for me I guess...I'm conflicted for sure xD
You're all making some good points.
