Questions about the 2nd movie (SPOILERS)

Puppet possession: I've not been that up to date with fnaf lore as of late but in games the puppet can't posses people right? Like I didn't like that choice because I thought it just didn't make sense with lore but I wanted to check.

Puppet character: I thought the puppet was a protector spirit and not a wrathful one, wouldn't golden freddy make more sense?

Afton motivation: I thought Willy A's motivation for killing kids was CC's death and his revenge by killing Charlie, is that still the case?
