I think we should start with better understanding how much life is complex in general. Our ideas and our way of being are a product of education, culture, society and the historic period we live in. But still ideas don’t exist themselves like an entity, they just illusions and products of mind. When we see other acting or thinking in a way we perceive as wrong, we should always remember that right and wrong aren’t absolute and never changing things. We can agree that right view, right action and right speak are conductive to the path of enlightenment in a Buddhist sense, but still those aren’t absolute and should be pondered case by case. For being compassionate towards others, we should first of all not be attached to our own idea of right or justice, and then understand why people may think in a specific way, and how often we too can get attached to our own ideas, even if these are for the benefit of the others.
