Not a bad cat. Cat trying to convey his desires to humans that don't understand his language.
There's several reasons for not eliminating in the litter box; he could have a UTI and squatting in the litter box might hurt, he may not like the litter, if the litter you use is scented, a lot of cats don't like scented litter. He might not like the texture of the litter. You might have to try different types of litter; clay, pine pellets, paper shredding, dirt.... I recently changed my cat's litter to paper shredding, and they love it so much they sleep in it when it's clean, lol. But it's completely unscented, easy to shift and move around, and that's what cats like in their litter box.
He could have kidney disease; cats with kidney disease often don't have control over where, or when they eliminate. It just kind of happens on wherever they happen to be.
Males also scent-mark, a LOT. That's in their nature. He might feel, being in a new house, and even in his old house, that he needs to claim his territory. Again, and again, and again. Judging by what you've said of how he does this, I think his reasoning is probably the scent-marking bit.
You could try adding more litter boxes, with a different type of litter in all of them. He might start using one with a particular litter in it, and from there you can change all the litter boxes to that litter.
Also, for some reason, he may WANT his litter box to get dirty, to feel satisfied that he's done a job well done with marking his territory. Constantly keeping his litter box clean might actually be causing him to feel the need to mark his territory in other places. See, the thing about litter boxes, is they wipe the scent clean. You scoop out the poo and pee clumps, and once a week you wash the entire thing. No scent. The only way a cat has true knowledge of having put his scent there, is by visual memory, no scent to go by. And for some male cats, maintaining their own scent in their own environment/territory is vital.
I think what you should try is buy more litter boxes, put different UNSCENTED litter in each, and spread them all throughout the house. Also, whenever he eliminates in a litterbox(s), don't immediately clean it. You might not like it, but let it sit there for a few days. You might actually find that he'll stop eliminating wherever he pleases, and you might actually notice him calming down, satisfied with the knowledge that he's marked his territory in this foreign place. Especially, with you, being new to him, that could also be the other reason he's so rabid about scent-marking. You're another male, and thus competition for "his" woman, and yes...cats know the gender of their people, human males and human females also smell differently, especially to creatures whose sense of smell far outranks our own.
Some cats are fine with their eliminations being immediately taken away, other cats, like your rabid little furball, NEED their eliminations to stay there as a form of acknowledgment. "Yes, okay, I've been here, good, good." Especially male cats...you must expect, when you take away the male cat's, uuhh....scrotum by neutering them, you generally take away their mentality to spray to mark their territory. Which is good! Don't get me wrong! But you must expect, as the unfortunate, but much more manageable part of that, for them to mark their territory in a different way.
Obviously I'm not saying to leave the messes he makes on the table and pile of clothing and stuff, that would just be...gross and unsanitary, lol. Keep cleaning up the messes, and give him a firm, "No!" when you see him do it. You cannot scold an animal for doing something that's already been done, you have to catch them in the act or else the scolding means nothing to them. If he's already done it and you weren't there, just clean it up, without a word to him. I'm thinking, with all the litter boxes, and any litter box(s) he eliminates in maintaining his scent for a few days, he'll get the picture of where he needs to eliminate.
