Magnus Vinding defends suffering-focused ethics based on various non-consequentialist views in sections 6.6-6.12 of his book, Suffering-Focused Ethics: Defense and Implications, and argues for reducing s-risks in the same book as a consequence of suffering-focused ethics. I donโt think he argues directly for reducing s-risks specifically based on these views (rather than generally reducing suffering), though, and Iโm not sure these other views would recommend reducing s-risks over other ways to prevent suffering; it would depend on the specifics.
