I don’t fully understand the second part of your question, but to answer the first: it’s neither good nor bad being a nonreligious person. A person can perform acts of altruism and help others regardless of religiosity. But if you want to get technical, it can go both ways at the two extremes.
Religious fundamentalism can be bad when people use religion to deny science (e.g. evolution) and human rights (e.g. marriage equality). Of course, not all religious sects view these issues the same way. Even within Christianity, different denominations are more resistant to science than others. Likewise, some denominations are less tolerant of homosexuality than others. In scarier scenarios, some countries criminalize homosexuality and atheism for religious reasons. Yet, others (usually moderates) use their religious beliefs to promote social well-being. And it’s no secret that religious organizations are very effective in organizing charity events. On the personal level, religion brings happiness and meaning to the lives of many.
Atheism, agnosticism, or simply a lack of religiosity, too, can vary in degree. Some atheists/agnostics don’t bother with religion at all. They live their lives as any other person would, enjoying all that life has to offer, but without a need to appeal to religion to find meaning in their lives or for moral guidance. In other words, they’re good without god. Some atheists/agnostics—as I can tell from YouTube comments and several atheist forums—seem extremely bitter and aggressive toward religious belief to the point where they accuse religious folk of being ignorant or stupid. I’ve also heard people say that atheism ultimately leads to nihilism, but I’ve never heard of anyone who is like this (other than in fiction).
So yeah, I think it all boils down to the particular individual and the intensity to which he or she subscribes to his or her creed. At this point it’s only fair to admit I’m not a religious person, but I’ve attempted to answer your question by putting my personal biases aside.
I hope I provided you with an adequate answer. Thank you for your question!
