For good people to do bad things...

[Oldandeasilyconfused]

But for good people to do bad things, it takes religion.

Bollocks.

Good people use religion to rationalise the most appalling acts.Without religion,they would find other excuses (such as "the national interest")

Some very nasty things have been done by large numbers apparently good,ordinary people under atheist regimes such as Fascism, Communist Russia and the PRC.

MY perception is that virtually any human beings is capable of any act,given the right circumstance: sufficient personal gain, or sufficient fear.

Atheists as a group have no claim to the moral high ground.
