Will they ever reveal Charles Lee Ray's childhood?

I'd like to see his childhood and how he became a killer. They already explained why Micheal, Jason, and Freddy kill people but not Chucky. All we know is that he was friends with a family and he killed this woman's husband and then kidnapped the wife and stabbed her in the chest when she told the cops on him for killing her husband and then her baby girl was born a paraplegic but we never got to see his childhood and why he kills people. I know in Seed when Glenn asks why his parents kill people, Chucky says it's a hobby but we don't know why Chucky kills people in the first place. For the next film, there needs to be flashbacks on how he was treated terribly by his father and the other kids at school kinda like they did with Freddy during flashbacks in the 6th Nightmare on Elm Street film. I also heard that Brad Dourif might also play Chucky's father in the next film so they could possibly reveal some of Chucky's childhood in the next film.
