Sammyjoe: This is a great question. For me, as others have mentioned, hope that i would that i could withstand such a nisayon. Truth is that there are times (usually after something scary/sad happens. Like what happened with Leiby Kletzky, Suri Feldman, etc…) that my imagination runs wild and i imagine myself in an accident or being abducted or beaten by scary men if i wouldnt commit certain aveiros (every time its something different). The situation feels so real sometimes and i actually feel scared and threatened or i’d feel strong and victorious.
In a time of shmad, we’d have to give up our lives. But what about nowadays?
