I might get everything wrong but my guesses are: - I doubt that this is important, really, but I think he was innocent while the REAL murderer was still on the loose - I think Marionette was left in the FNAF 2 Building, aka why he isnt in the Maingame in FNAF 1 nor FNAF 3 (at least physically) However, in HD he appears to be the only one not wearing his mask - until he ascends into afterlife. I think this means that the Spirit of the boy left the other building - obviously leaving the Puppet (Phone guy FNAF 2: " and it can go anywhere") - and joined the other Spirits, who were unlike him still bound to their suits, in the FNAF1/3 building where they all set free. the puppet mask that appears then is in my opinion just a hint left to symbolize that the bodless spirit was the Puppet - I really doubt that he killed more kids than the 6 that are shown in the black and white part of HD. I'm gonna take a wild guess and say that HD actually includes 2 time Periods: the colourful part with the 5 children and the puppet spirit is the day of the killing. The Puppet helplessly observes the kids while prob. knowing what is going to happen to them. Then the black and white part is years later, when the children's spirits are finally freed. I actually dont think that there have been kids killed during FNAF 2. Because just think about it, if there were dead children/ missing children would the Restaurant REEEALLY be allowed to hold one last birthday? Especially since the same already happened in the old location? Even if you accept that game logic doesn't always make sense, I don't think any parent would have allowed their child to go to this party. Also nothing in the Phone guy's dialogue directly implies that there have been kids missing or smth. I believe that they just have found evidence/ the kids bodies that were never found. I'm not quite sure what happened, but I believe the investigation etc. might have brought up the idea that the original suspect wsn't actually the murderer and the purple guy was still on the loose. The animatronics were tstirred up due to all of this (hence the starring) I think for some reason the Purple guy then decided to visit the pizzaria again. Maybe to hide evidence? To still his bloodlust one last time before his capture? To dismantle the Animatronics? Anyways this is why he sometimes appears during "Save them". The bodies in SAVE THEM are either just hallucinations/ Flashbacks OR the actual old corpses of the children murdered in the old location (Hence why they've been described as having mucus and blood around their openings in the Newsarticles in FNAF1, but being without corpses in FNAF 1 & FNAF 2 = They were originally in the old suits but then taken out and left to rott in the new location. Implying Purple Guy worked back in Freddy Fazbear's Pizza 1 and in 2. so that he could have hidden this fact from everyone for a long time. After it was discovered, obviously the old employees were suspcted first (Phone guy: no one is allowed in or out, y'know, especially concerning any...previous employees) and Purple Guy most likely fled (PG:a position just became...available) just to return the next night and missuse the Golden Freddy suit in some way. (Maybe that was the only body he could hide for good or smth?)) - Since he came back after FNAF 3, my guess is that he heard that the Animatronics killed a security guard and became paranoid that they somehow might get back to him (Since after the shutdown there is no one left to guard them). So he wants to destroy them before they can kill him/ to calm his nerves or whatever. Obviously it didn't go as planed. - I guess thats just because its telling the Story - If the kids got their peace or not doesnt matter for the events in FNAF 3 because they would play out this way regardless of either option. Springtrap is the only thing that can really kill you, and he would be haunted in either case since Purple dies in both ends. The others are all either 1) set free - and therefore a figment of your imagination, 2) Still in the animatronics, but unable to move and therefore kill you. Also, since their murderer is dead they prob. wouldn't actually have a motive to kill you and just act like Golden Freddy in FNAF 1 without the killing part.

I'm pretty sure I've just blabbled a lot of shit that conflicts with 50% of the games lol, but I tried.
