Religion is an insult to human dignity. With or without it you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.
This kind of radical imagery is necessary if we (religious and secular people of good faith and intentions) are ever going to shatter a cultural symbolic order that seeks to lessen the suffering of others. We ingest this symbolic order through benign daily conversations, and the ideas and images disseminated through television and other forms of media. We are being consciously and sometimes subconsciously conditioned to see some people as less than us.
