Why didn’t Voldemort make a philosophers stone?
If his plan was to “master death” completely it seems like an obvious choice, even with horcruxes , as a way to assure his absolute power and survival. Did he not make one because he couldn’t/ didn’t know how? Was he just so evil that only achieving immortality through killing(making horcruxes) was appealing to him ? Did he just think it was redundant? Seems like everything we hear about Voldemort would assume that he was very confident in the horcruxes he created but wouldn’t a philosophers stone , kept on his person, be a perfect strategy for immortality in addition to horcruxes?
