How do you stop evil from winning? First, you have to notice that someone is suffering. Then, you have to evaluate if this is self-inflicted suffering (in which case you put them in rehab); or, if someone with power, or the power, is the primary controller of the suffering. Then, when that’s established, you get to exercise your knowledge of G-d, and for your eternal sake, be a hero, or at least not aid and abet.
