Hoarding is a mental disease and mitigates my hatred of that murdering puke just a timy notch.
My mother lived a tidy life by herself in a seniors apartment complex. Then one day my sister dropped in to visit her and was blown away by the amount of crap in the place. You could barely move and it wasn’t junk it was supermarket items that she kept buying over and over again. They got the place cleaned out but she kept doing it until they had to move her out and into another complex where she could be watched every day. She’s lucky she had family to watch out for her or else she would have ended up suffocated in her own garbage. It sounds like that man was going the same route.
