If I believe morality is subjective,can i still call things wrong?

I’ve been skeptical of religions for a long time, and one of the reasons (though not the only one) was my belief in objective morality. I used to think morality was not just an opinion but something factual, that values existed in themselves. Because of that i rejected religious scriptures,since i found some things in them morally troubling.

But over time after seeing different perspectives and learning more i came to the conclusion that morality is subjective.

Does this mean i can’t really criticize religious scriptures or people’s actions as being “wrong”? For example if someone kills a child can i no longer say “that’s wrong,” since morality doesn’t exist as an objective fact?
