Yes he wants to resurrect his dead sister, but he also wants to cause as much pain and suffering as possible because he blames the world for her death.
Obviously the world was no all responsible but he was groomed by his absolute woman moment of a mother and completely absent father to worship his sister like the rest of the shitty cult his mom was running.
Modern medicine can't bring humans back from the dead but anything is possible with relic technology, plus he can cause the maximum amount of pain and suffering possible with said technology at the same time.
Now if you ask me who the fuck the version of his sister he was talking to at the end of slow shock was, i dont really know. I guess in his plan to get one of the doll geniuses to use her brain scan on a doll and then use that brain scan to activate a relic capable of bringing her back (???) too much of the doll got throw in the mix and now the sister has evolved beyond the individual he wanted to bring back originally, who was a fucking deranged retard like their mom
