I cannot countenance the sort of mindset people have, that always seems to grant the offenders / perpetrators the concern they never showed their victims.

Because if that is not done we are no better than the offenders.

I don't think I believe in the concept of evil, as suggested earlier to some extent it implies an outside cause.

However there are those who lack the inherent morals that any social group requires in order to flourish as well as those who lack or have a lower level of empathy towards others.
