Do we have to do good?

[Angel]

I often here some proponents of objective morals use what would work good (to them, to society, to both) as one justified basis to determine if objective morals exist and what they are. Okay, even if I knew what some good things are, is there any objective reason to show that I'm obligated to do good or that I should or in other words that it is good to do good? One thing that I've thought about is that if there's no free-will, then we can't be good because we 'want' to be good but we can only go by our nature and some people are naturally mentally ill.

With that said, is there any way to prove or objectively show that mankind has to be good?

If nature (lets just say our nature and Mother Nature) can and has produced or caused mankind at times to live disastrously or has and will cause natural disasters (i.e. famines, floods, the ultimate state of the Universe i.e. heat or cold death, etc) doesn't that go against any arguments that we should do good?


I'm not advocating for nihilism, but I at least want to know any logical justification for why anyone has to do good other than because society tells them to.

We don’t HAVE to do good. An ‘ought to’ does not necessarily logically follow from an ‘is’. Just because someone is starving doesn’t mean you ought to help them.

I agree and I think I may've confused the two in my question. I believe any objective morality would have to consist of both an "is" and an "ought" at least when it comes to if objective morals exist and that we should do them. Otherwise I don't see any reason for why God or nature (the only two argued for positions for the source of objective morals by far) would have a moral code. If someone asserts that objective morals do exist, they should also have the burden of also including in their justification why we 'ought' to follow them.

None whatsoever. If one chooses to believe in God, one can come to the conclusion that good objectively exists. But one cannot objectively show what that good is, or objectively show that it matters for someone to actually do it.

But I think if someone believes that there is a good, they will usually do their best to do what they think is good. With some exceptions of course.
