If you want to inspire children to virtuous religious lives, choose positive stories. Children are too young to decide to die for their faith, and not mature enough to decide when it may be appropriate.
It doesn't matter if you are Catholic, Protestant, Mormon, Muslim, Jewish, Hindu, Animist, Atheist or whatever. If children aren't old enough to decide for themselves if they should have cookies or candy for breakfast everyday, then they are not old enough to decide whether the religion taught to them by loving parents is one they should die for.
In grade school, the nuns taught me a song "Faith Of Our Fathers" in which we sang how "sweet" it would be to die for our faith. Not one of us had any idea what death was; we were just singing what we were told to sing. This is not teaching a holy faith; it is programming an unholy martyrdom (and luckily, it didn't take; I don't think the nuns really wanted it to.)
When you're an adult, then you can make adult decisions. Teaching children that they might want to die for their faith is a bad idea. There are many more positive books for religious children.
