Yes, though I think equally, and maybe the more effective aspect of the prohibition against chemical warfare was the general recognition that going down that pathway would be much more awful for everyone than sticking to conventional methods. This is partly why Germany pretty much avoided using them in warfare during WWII: Once the genie was out of the bottle they would lose any advantage obtained in their initial use. (I don't know if it's apocryphal, but apparently Hitler also disliked them from his own experience in WWI)
