Actually no. Epsilon made it clear that he wanted/needed to die in his message. He says that he gained (from hanging around the BGC) helped him form the personality of Church but it is also holding him back.

That is mainly the reason he died - because with this personality, he can not be a true A.I. This is shown with Carolina when he couldn't run her equipment, even though he says he's just a fragment it's a hint to that he probably was achieving metastability, becoming Church (which is loosely a person).

That's my take on it anyway.
