Not OP but occasionally I come across videos of 'animals behaving really badly' so I did a quick search (below). I think we all know about male lions killing cubs that don't belong to them, dolphin's dark side, etc...

I remember getting into a discussion with someone about religion. This person hated religion. I'm not religious. He blamed religion for all the atrocities in the world. I wasn't defending religion but I like to look at both sides and said...

Maybe it's because of religion that we haven't already destroyed ourselves. At least with Christian (new testament) religion (the only one I'm passably familiar with), there are a set of rules to live by[0]:

No killing, no adultery, no stealing, no lying... etc.

** Please, I don't want to get into a religious argument. **

But, what if... religion was _invented_ by man because man himself was so murdery and rapey as OP (afpx) stated. That the only way to control him/her was by inventing a power greater than man himself. Indoctrinate man at some core level so that these tendencies could be managed somehow.

Perhaps we have come into a period where religion's influence is not needed as it once was. Perhaps we are in some transitional period. All of this is supposition for discussion (not argument), please:-)
