This is a hard question that only you can answer.
But I can give a tip:
You need to think about what your moral code is, and what has priority over what.
It sound like one of your rules is not letting fear influence your decisions.
I have a similar rule. If there is no risk of death, fear is not allowed to be part of the decision.

I think it depends. I know some people who care about friends, partner, boy/girlfriends, ect., would likely prefer to make a educated choice knowing all the information they can. But sometimes, if the person in trouble feels like they may be putting someone in danger, it can be different. However, true relationships are built to last, and that's the most important thing of all. That's the best I can say without knowing more of the situation.
