Rectifying Negative Energy of Amalek
King Shaul tried to sacrifice the livestocks of Amalek. It seems that he wanted to tikun negative energy of Amalek. But it made HaShem angry, and ultimately HaShem took away the kingship from Shaul. Is it impossible to tikun negative energy of Amalek? Is there any specific yetzer hara which is impossible to be tikuned?
