I did not know about him. From what you have posted, the first few words that come to mind are "satanic", "malevolent", and "negative". It seems very obvious to me that this artist is depicting these things as bad, using classic depictions of pure evil alongside sexual acts that are widely considered taboo. It seems to me that his primary aim is to demonize these acts, and paint those who partake in them as agents of the devil or some equally malicious and evil force. The only other explanation for the subjects of his art are that his goal is simply to be edgy, and that the only value of his work is the shock on the part of the audience.
In either case, I think his work is of low quality. If it isn't clear, it is because his work is shallow and from the numerous examples you have provided, often of low quality from a technical perspective as well. I am left to wonder why you have so many of these works saved to your harddrive, and why you so readily provided information on finding more scans of it.
