(Sorry if this was already addressed, I didn’t read through the whole thread)
Say a Tinok Shenishba is in a Frum neighborhood and wants some lunch so he goes to a Kosher pizza shop and eats his lunch. His intention was eating lunch, not eating Kosher, would he get schar for eating Kosher food?
Going a step further: Had he walked into a non-Kosher store and had something, he would have gotten an aveira. If he didn’t care about the pizza being Kosher, and there had been a non-Kosher store for him to walk into, he would have eaten something there. So if his eating Kosher pizza was never “recorded” as Kosher, would it be considered Kosher or nothing? (To make it a little clearer, since he didn’t have any machshava to eat Kosher, even though he did, would it still be considered his having eaten non-Kosher food?)
