On a ‘hashkafic’ level it doesn’t work this way. Each person is accountable for their OWN actions. HOWEVER, using the communal responsibility of ‘all Jews are responsible for each other’, you are correct that EVERY Jew has a collective responsibility to make everyone the best they can be.
EXAMPLE: Joe was bullied by his classmate, Chaim. The school did nothing to Chaim because his father was the Chairman of the Board, and instead blamed Jow for not being able to fight back. After more hypocritical situations, Joe left Yiddishkeit. Joe is responsible for his actions (he will likely be found Not Guilty due to mitigating circumstances). At the same time society who allowed the administrator to remain, Chaim the bully, and the board who allowed Chaim’s father to remain it’s Chairman are all COLLECTIVELY responsible for the outcome.
On a PRACTICAL level, there are very few people who are willing and able to be Nachshon and jump into the water against the tide. All COLLECTIVE/GROUP THINK BEGINS WITH AN INDIVIDUAL. There is certainly movement and an overwhelming agreement among many in the frum world against abuse of all types.
