Agreed.
Religion basicaly says that one should act a certain way because a particular deity wants you to and will punish you if you don't.
The ethical standpoint of morality basicaly says that one should avoid causing suffering to others. There are several reasons for this, one is remorse, causing the suffering of others can lead you to experience uncomfortable emotional responses. Another is that of revenge/reciprocation, if you cause another to suffer, he/she, or others, may in turn wish to cause you to suffer.
Interestingly, one thing that is almost universal in religion is the 'Golden Rule', which is based upon reciprocation and in it's basic form states that you should treat others as you wish to be treated yourself.

The Golden Rule is one thing that religion got right. It's a formula for universal peace that's elegant in it's simplicity, if everyone followed it, there would be no crime, no abuse and no wars, but one doesn't
need religion in order to learn this very simple lesson. Many ancient philosophers came to exactly the same conclusion without turning to religion.
