I feel that losing faith in God ultimately made me a better and more moral person. As a Jehovah's Witness I let the WTBT define what was moral. Since I don't have anyone telling what is right or wrong I have to give it a lot more thought. I am still moral in most of the ways that that is defined in society, I don't lie, cheat or steal, I didn't need religion to tell me that.
I also think more about how my actions affect others, I guess you would call it the nuances of morality. I seek in everything to be kind wherever possible, to seek out the greater good, to give something back to society when I am able. My goodness isn't measured in field service reports, or magazines sold or not celebrating holidays, but it is in my soul, I know when I am being my best self, when my actions match my values, that is what being moral is to me.
