After WWI, chemical weapons were more looked at as a deterrent similar to nuclear weapons. NATO in fact made sarin a standard part of its chemical weapons stockpile from the 1950s through to the 1970s. As did the USSR.

I find often when it comes to warfare, morality changes as weapons and tactics become obsolete. They were considered fine when only the major powers had them. We like to think that we have just become more humane, but I think we have just become more efficient. Once everyone has drone technology, there will probably be a move to ban those as well.
