You may find it terrible, but I actually believe in objective reality. I believe I know good and evil when I see them... and I can do this without access to the supernatural or recourse to religion. I believe in better and worse outcomes for individuals and for societies. I believe some societies are better than others, because I've lived in 34 countries over 20 years and I can make honest comparisons about the pros and cons of each. Nowhere is perfect, but some actually are better -- objectively, if you believe that being expressive and embracing diversity and freedom of thought is a good thing. Personally I think good==complexity and evil==destruction, and so anything that kills life is destroying complexity that the universe demands, so is necessarily a kind of evil.
The Achilles heel of people younger than me is that they think opinions on the internet actually mean something... and the younger they are the less they seem to believe in the objective truth of the world. Call it the corrupting influence of Instagram, I guess. But I think it's due for a major backlash, because no one wants to have their morals dictated to them that way... and the objective world remains. It always remains. True things are true, false are false; evil is hypocrisy, and it's rampant. It is not a subjective, religious pronouncement.. it's a thing that is fucking right there.
