It is not society which is failing when people turn to murder it’s the people who turn to murder who are failing.
The focus should be on why a few people decide it’s okay to hate other groups of people so much, that they murder them.
To believe it’s society’s fault people are turning into murderes and now it’s society’s responsibility to dissolve each and every problem anyone could have ever is completely unrealistic.
People will always have problems. And there will always be people who believe other lives are worth less. It’s much more likely to be able to do something against the latter than doing something against people having problems.
