On it's own, morality is humanity's attempt at creating a ruleset for society that promotes cooperation for survival, rather than a society that thrives on power and influence exclusively. Religion ultimately twists this for control over its worshipers in the worst cases, which is pretty ironic.

We're uniquely capable of contemplating the consequences of our actions thanks to the sheer luck of having complex brains. Working with your neighbor on a hunt, rather than fighting him to steal his captured game, would likely be more beneficial in the long term. Nothing about the content of our collective morality is special, but more or less convenient, and the things we think are "bad" could have ended up as "good" if they had worked out favorably.
