In which broken society do you live where this is true?
I would say drawing sexually explicit pictures of real persons without their consent and keeping them in your drawer is neither illegal nor morally reprehensible in most of the world.
I would personally not tell them because not everyone likes to know what/that others think about them. But I do not see the moral issue if I don't tell them.
What if I only thought about it? Still morally reprehensible? Or only if I tell others I think about them? Then you could argue it's sexual harassment.
I don't think one internet commenter can know or decide what is or isn't "morally reprehensible" in "most of the world". I don't speak for "most of the world" but I'm fairly sure "I drew nudes of your mom lol" will not go down well anywhere.
I am with you on publishing these...
