The probable idea that humanity could maybe change itself?

In other words, could some of humanity in general update it's thinking and reasoning and respect society as a whole?

Or should society in a sense reluctantly continue to cope and deal with how some treat others, because things are as some have continued on activity wise decade after decade?

(Meaning that maybe in a sense some in society have become desensitized to some of the goings on around them?)

Some examples; Assualt and battery, hit and runs, abductions, robberies, carjackings, domestic violence, bullying, and so on? 

So instead of asking society in a sense to change itself for how some treat society via an individuals questionable choice or choices, why not give society as a whole the benefit of the doubt instead?
