Whitesnake's discs probably don't work on ghosts, but Pucci could insert the Limp Bizkit disc into someone and have them revive Arnold. IIRC Reimi didn't see Kira too well because it was dark, or he stayed out of her sight, but Arnold probably saw him. Memory discs should work on animals since he uses one on a frog in chapter 49. Even if none of that works, Pucci's ability to read others' memories makes it far easier to find out someone else's identity than Kira's. Also Whitesnake's range allows Pucci to fight from a distant, where as Killer Queen has no ranged attacks w/o Stray Cat (excluding Sheer Heart Attack which has no accuracy. Kira would have to be extremely lucky to defeat Pucci with it). Whitesnake could easily steal Kira's Stand Disc before Kira could learn Pucci's identity and kill him.
