'Evil' in the Bible

Then in his fury, the king stood up from drinking wine and went into the palace garden [to decide what he should do]; but Haman stayed to plead for his life from Queen Esther, for he saw that harm had been determined against him by the king.

Then Esther spoke again to the king and fell down at his feet and wept and implored him to avert the evil plot of Haman the Agagite and his plan which he had devised against the Jews [because the decree to annihilate the Jews was still in effect].

For how can I endure to see the tragedy that will happen to my people? Or how can I endure to see the destruction of my kindred?”
