Mephisto

the Lord of Hatred, is the oldest of the three Prime Evils. Many claim that Mephisto is the most intelligent and cunning of the Prime Evils. There are some who believe that if there is truly a leader in Hell, it is Mephisto. There is certainly evidence that Mephisto himself believes this to be the case, declaring that "where I am is Hell." It is said that Mephisto was most adept at pitting his brothers against each other. Diablo and Baal chafed at his manipulations, but more often than not they complied. Deckard Cain speculated that this was because Mephisto provided them with ample opportunities to pursue their ambitions. Perhaps because of this, Mephisto is seen by some to be a unifier and great tactician. It was Mephisto's greatest ambition to pit entire societies against each other, to turn brother against brother, to seed discord and distrust wherever he could. Mephisto shuns companionship, considering it "a comfort of the wretched."
