Curiosity killed the cat. Or so they say. The funny thing about that is cats have nine lives right? So even if curiosity killed the cat, I bet that cat pretty well satisfied his curiosity before he died all nine times.
Moral of the story everyone has a conscience, everyone knows whats right and wrong and everybody can tell when they've pushed too far.
That being said, satisfy curiosity, ask the tough questions, when something is sitting there daring you to figure it out, don't sidestep the problem. Don't find workaround solutions. Try those solutions that make you curious. You may just be surprised.
