Can an atheist be ethical like theists

[Redbeard The Pink]

Well you can search the word ethics and read in wikipedia by example that ethics came from relegion even in ancient egypt.

As for that point if you don't like somthing being done to u .........etc
That's also a comes from relegion but let us assume it is just logic and common sense no more then that means that your understanding of ethics will evolve with the society development and according to what we see these days it is in bad direction not good one.
In human nature people never assume that somthing is bad unless it hurts someone else so robbing a bank which is a public Institute wont be that bad for example because ur not hurting anyone.

Ok, I just searched the term "ethics" and checked what the Wikipedia page says about it. Religion is barely mentioned, and in no way does Wikipedia suggest that ethics is always or even usually sourced by religion. That assertion is horse shit.

As for the rest of that...let's see, where to start.

First off, as I see it, human ethics in the broad sense is improving, not worsening. While there will always be setbacks, human rights have grown by leaps and bounds in many places in the last few hundred years, and bigotry and religiosity are on the decline in general. Hopefully, within the next few hundred years, religion will be a dim memory living on the fringes of society.

Your assertion that bank robbing hurts no one is also not correct. This, again, boils down to this awesome super power I have called empathy. I don't rob banks because I don't want to go to jail for it, but let's say I believed I would get away with it. I still wouldn't want to do it because I can put myself in the shoes of the bank workers and manager, the bystanders in the bank, or any number of other people and see that robbing that bank would cause others to suffer. Based on this, I can make a moral choice not to rob a bank, even if I'm not scared of jail or Hell.
