Cat Lady kind of reminds me of a 1990s point-and-click game from Empire Interactive, Dreamweb. You were tasked by the keepers of the Dreamweb to kill seven people who would be responsible for a nuclear war, but the way the documentation and the background story was written, it was ambiguous as to whether you were saving the world or were just a serial killer driven by paranoid delusions. The game ends with you walking into a police ambush and being gunned down.
Dreamweb also had an excellent soundtrack from Matt Seldon.
