Usually the answers are the same. People feel empowered most often by the prevailing attitude of their societies. If we want to see less of something then we (all) need to speak up against it. Can we raise our hands when someone asks us if we ever went against prevailing culture and stood up for someone (or ourselves), even at a grave cost?

Also some are psychologically disturbed due to various reasons and those people need therapy and mere reactionary punishment will not improve matters in the long run (for society).
