WHY IS MURDER ILLEGAL?

There have been way too many times since Dem Der moved in that I have wished that murder was legal. These are but a few of the capital offenses he has commited. He has never once put the bog seat down. Not a once. He leaves shampoo blobs on the shower floor and has a shaving foam covered can of shaving foam enshrined in a place of honor among my purple shamoos, soaps and stuff. He has gone through an amount of bog roll that I have trouble using up in 6 months in less than one month. And that's just the bathroom!
As far as the kitchen goes, he thinks that paper towels were made for drying dishes, pots and pans, and if it runs out that bog roll is a worthy substitute. A 6 pack of paper towels lasts at least 6 months when it's just me. He leaves empty packaging and wrappers in the cupboard and there's a crumpled up piece of paper towel on a shelf in the fridge. There's a little waste thing in the sink with a bag in it for the gunk that's left in the sink after doing dishes and he puts used paper towels/bog roll in it instead of the bin under the counter. When he can be bothered to use the bin, he can't be bothered to push the stuff down far enough so the flip top on the bin cover will close properly. It's also perfectly ok not to close cabinet doors so that not quite awake gimps can walk into them.
The dining table is adorned with his most recent purchaces, which does nothing by way of helping me get over my habit of dumpling things there. I no sooner get it all cleaned off than he's filled it up again and added duboius pieces of paper towel/bog roll.
He's invented a new security system to keep intruders out of his room. Rather than use the external latch and lock that *I* put on the door, he uses a system of fallen or dropped broom and dust pan with crossed handles. How he gets in and out without tripping over them, must be part of the genius of his invention.
There are no words to adequately describe the room he lives in. I'd take a picture, but I fear for the camera lense!
I don't suppose I could claim murder in self defence?
On the other hand, the poor guy does try. Any time he leaves his toxic waste dump for other regions of Gimp House, he does ask if he can me anything. I'm spending rather more time than usual in bed as that little slit neck thing has left me feeling more like Wimp Gimp than Wonder Gimp. Who would have thought it would take so long to start feeling like my own unusual self again? All they did was slit my neck, do some fairly simple plumbing, staple me back together and send me home. So why am I so tired all the time? It's not the pressure sore because that predates the operation by a good 3 weeks.
Israel is going though a miserable cold wave with night time temps under zero for most of the country. That's 32 for you Farenheit users. No rain, so no cloud cover to keep the air warmer at night.
