Narrative:

Aircraft X was descending into the clt area. Aircraft X was leaving 28000 feet for 24000 feet on the star to clt. We had moderate turbulence and icing from 24000 feet to 26000 feet. I descended aircraft X to 23000 feet to get him out of the icing and turbulence in the area. I didn't want him to hit the turbulence. That is the reason I took him to 23000 feet right on top of aircraft Y at 22000 feet going to clt on the same star.the aircraft were stacked on top of each other with speeds assigned to get spacing for the airport. I told aircraft X to maintain and cross burrz at 23000 feet; to keep him separated from aircraft Y. I coordinated with atl center to let them know the aircraft X was only descending to 23000 feet and not via the arrival. I switched both aircraft to atl center. I then noticed aircraft X descend through aircraft Y.we as controllers have so many things to do; to make sure the pilots knows about the weather; notams; icing; and all other things they might encounter that it makes the controllers job that much harder; knowing that we are held accountable for everything that goes wrong. If I was not worried about the turbulence from 24000 to 26000 feet I would not have taken aircraft X to 23000 feet. If he was stopped at 24000 feet we would have had more time to catch the mistake and fix it.stop having the NTSB dictate how we do our jobs. All these requirements they have for us to do. Calling out weather to aircraft; turbulence reports; on top of our job of moving aircraft and spacing them. Controllers have enough to do; without all the extra work we don't have time for.

Title: ZDC Center Controller descended an aircraft to 23000 feet with traffic below at 22000 feet. After issuing a frequency change to the next sector he observed the aircraft descend through the altitude of the lower aircraft.
