in AC 3DS you find out that redd kept selling fake paintings because he wanted to be an artist, but he was only good at imitating artwork so he failed miserably and changed his business to the black market so he wouldn’t starve to death and so he couldnt support his wife Kaitlin and daughter Katie. All the fake paintings you buy from him are his failed artwork.
