Lust

Fitting in with the core definition of lust, being the excessive desire for something immaterial, over the pop-culture definition of sexual desire, Lust is a being of "bloodlust," craving violence, pain and murder. Notably more sadistic than her siblings, Lust displayed distinct pleasure in torturing her opponents and making them suffer, such as during her fight with Roy Mustang and Jean Havoc in Research Laboratory 3,[1] being the only Homunculus ready to murder Alphonse and Elric in spite of their importance to Father's plans, something even Envy is hesitant on, her death being a brutal torment from a man that wanted her to suffer and die, and spending her last moments stating her appreciation for being killed by a man like Mustang and almost sensually wishing for his agony, a situation that came about due to her purposefully leaving him to bleed out.
