A two solar mass black hole would take 1.2x1067 years to evaporate. You can compare this to the total age of the universe of 1x1010 years. Maybe this gives you some idea of how inconsequential Hawking radiation is in the scheme of things.

As a BH hole evaporates it's entropy decreases but the radiation gets randomly distributed in the external universe, and the total entropy of the hole and the universe goes up just as the second law demands. There is nothing mysterious about this.
