It's very sad to me that despite Harley Sawyer being a fan favorite he's so horribly misunderstood by the fandom. YES he is an evil scientist, but acting like he's generic or doesn't have a solid or interesting motivation is silly. We see in the ARG that he was practically "groomed"(for lack of a better word) into the role, Playtime Co saw the potential he had for their evil and they trained him to do so. And in the end, they punished him for becoming what they always wanted him to be.
Not to mention the implications that he comes from an abusive home, no wonder he turned out how he did. Obviously I'm not trying to excuse his actions(I LOVE EVIL MAD SCIENTISTS!!!), but there's so much more to him as a character than the fandom seems to care about. I think Poppy Playtime consistently has VERY fascinating characters that get boiled down to their most surface level traits - Harley, Doey, and Stella are all victims of this.
