one of the many reasons delita is one of the coolest characters in all of FF.

he saw how easily disposed low class people were like his sister. so his revenge is to become king himself and kill anyone standing in his way. all though you can tell he really doesnt want to kill his best friend Ramza despite what he may say. when ovelia betrayed him for whatever reason she had (that was the part i didnt understand) without hesitation he did what had to be done.
