Will deleting a pointer to an object in the destructor of a certain class automatically delete it from the heap?

Everytime I was coding a game, I always utilized this piece of code for the destructor:

A::~A()
{
    delete this;
}

Will this actually delete an object on the heap when the scope for it is over?

Doing this makes no sense as the destructor is called upon deletion of the object ( delete invokes the destructor), there's no reason to call delete again. In the best case scenario where the object you are freeing is actually allocated by new you are doing a double delete on your object. In the other case you are calling delete on an object not created by new. Both are undefined behavior.
