Zeref was obsessed with researching the nature of life, death and magic, which is where the designs for the R-system (Tower of Heaven arc) and Eclipse came from. He did this as he wanted to resurrect his younger brother, who had been killed. He was warned not to continue this research as it was against the sacred teachings of the god Ankhseram, but Zeref did continue. He was duly cursed with the 'Curse of Contradiction' - the more Zeref values life, the more lethal he becomes to people around him, but when he 'forgets' the value of life, the curse can be controlled. The curse also made him immortal.
