@anointed1: "A person who does not believe in god has no obligation to care for anyone whereas a person who believes in god feels obliged to care for others."
That sense of obligation isn't very strong it appears:
A 2012 study conducted by the University of California at Berkley found that compassion consistently drove less religious people to be more generous. For highly religious people, compassion was largely unrelated to how generous they were (a sense of obligation seems to be the reason). The findings, published in the journal Social Psychological and Personality Science, suggest that religion can actually make its adherents less compassionate, as they often judge the unfortunate as deserving of their plight.
In a 2015 study conducted by the University of Chicago, nonreligious kids seem to be more giving and altruistic. The study looked at 1170 children from around the world. Children from religious homes—particularly Muslims—also showed a greater inclination to judge someone’s misdeeds as wrong and punish the perpetrators. The study, the first large-scale analysis of its kind, suggests that religion and moral behavior don’t necessarily go hand-in-hand for children.
“Our findings support the notion that the secularization of moral discourse does not reduce human kindness. In fact it does just the opposite,” says Jean Decety, a developmental neuroscientist at the University of Chicago, in Illinois, and the study’s lead author.
