Do Human Need Religion?, some people say they can live without it (Philosophy)

I can live without it and I don't go kick animals into drains, stabbing people's back with gossips, robbing, stealing, killing, raping, etc...
In my opinion, religion is created long times ago to bring groups of people into order so they don't act barbaric/lawless during the time.

A human that grows up in a proper culture and environment doesn't need a religion to know what's right and what's wrong.
