Until you see the whole picture you cannot see the whole picture. We literally cannot stand in the exact same place as another person, so we will never see from exactly the same perspective.
Love will create positive change in our world; hate and aggression just continue the cycles we are here to transform. We cannot force someone else to open their eyes to compassion and love by bombarding them with hate and condemnation. Sometimes our focus on what that other person is doing is just our own ego's way of avoiding our own "inner work". We get so focused on "the crusade" that we forget the love that was in our hearts at its start.
History will repeat itself until we find a different way to respond and treat one another.
