Is Kant's categorical imperative same as 'empathy'?

“A categorical imperative, on the other hand, denotes an absolute, unconditional requirement that asserts its authority in all circumstances, both required and justified as an end in itself. It is best known in its first formulation:

Act only according to that maxim whereby you can, at the same time, will that it should become a universal law.”

Isn’t this simply empathy in a way?
