Game developers have zero moral obligations. You would never say "should a painter paint this?" A painter can paint whatever they want. Anything less would be censorship.
Now that being said, resellers such as steam or gog can choose not to distribute a game if it contains questionable material (as they should be allowed to).
Nothing should keep them from self-distributing their game however.
