A Jew b'shogeg cooked grilled cheese by lighting a burner under a pan on Shabbos. He meant to do it and knew it was Shabbos, but he didn't know the penalty for it, which is s'kilah God forbid. So it qualifies as shogeg. By lighting this burner, he thereby warmed the pot next to it that contained completely cooled off, fully cooked soup that was fully cooked before Shabbos. Would another Jew be able to eat this soup, even though it may have been warmed by the other Jew's forbidden act, and it probably was because the soup pot is warm to the touch from being heated by the burner next to it. Or would it possibly be mutar to eat it because the Jew would have eaten it anyway, even without it being warmed up.
