The Struggle to do Good

[brokenreflector]

I'm not sure why being an atheist matters?

Because if God doesn't exist, then there is no other ontological basis for objective moral values and duties.

So, from your perspective, there shouldn't be objective moral values and duties. Yet, you seem to think there are. You even stated a moral principle that you think is objectively true. It's poorly formed, but we can still use it.

"X is objectively evil if it causes harm to human beings"

Since you're an atheist, what or who is the source of this principle?

If that were the only reason you believed it, then yes..-your belief- would be subjective.

That's not what you wrote though. You wrote that X cannot be objectively true if it was told to you by a person. You seem to be backpedaling from that remark now, but I'm glad you're learning. That's a good sign.

Watching people get harmed, and being harmed ourselves.

So by watching people get harmed and being harmed yourself that somehow makes "harming human beings is objectively evil" true? That's just a non-sequitur. And there are people who derive entertainment and pleasure from watching people getting hurt. Does that mean "deriving pleasure from watching people getting hurt is objectively good," is true?
