A double action pistol does not load itself. Double action means that the hammer does not have to be cocked separately- pulling the trigger will make the hammer rise and fall- but you still have to chamber a round of ammunition first.
Yes
After a round has been chambered
Often with a semiautomatic pistol, once a loaded magazine is inserted and the slide racked, you now have a pistol that is ready to fire: there is a fresh round in the chamber, the hammer (or striker) is cocked. This CAN be a dangerous situation, if the shooter isn't going to fire the weapon immediately. In the past, a person would have to CAREFULLY lower the hammer while pointing the pistol in a safe direction. If they slipped, they would fire a bullet accidentally AND their thumb would get hurt--mashed by the recoiling slide & hammer. A decocking lever prevents such accidents by LOWERING the cocked hammer to a safe position. Once utilized, if the shooter wanted to prepare the pistol for firing, they would have to: Manually recock the hammer, if the pistol were a single action only type, or, manually recock, or utilize the pistol's long Double Action trigger, if the pistol was a Double Action/Single Action type.
A loaded pistol is not a toy. Any game with a loaded pistol is foolish and unsafe.
No. Strictly speaking, Glocks are "safe-action" which is a Glock proprietary term. Glocks are neither double action nor single action. They have attributes of both types.

A single action pistol, such as the 191A1 .45 Auto, requires that the hammer be cocked before the first shot. A Double Action pistol does not need to have the hammer cocked- pulling the trigger causes the hammer to rise and fall. Some are DAO- Double Action Only- the hammer cannot BE cocked, and must be fired from a "hammer down" position. These include the Para-Ordnance LDA pistols.
