I recall reading (though I can't find it) that the person who was punished for collecting sticks on Shabbat was actually doing so in an effort to help others see the laws of Shabbat in practice (or something "positive" like that). Is there a concept in halacha of creating a scenario to allow others to be mekayem a mitzvah?
Examples -- Can I be less careful with my belongings so that I can lose them and give others the chance to return lost items? Can I expose myself to illness so that more people can come visit me as bikur cholim? As an extension, if I choose not to have children have I deprived potential children from being mekayem kibbud av so by not creating the situation; have I added an aveirah?
