Evil are still humans following the same process of as us all they just with a different perspective. They have life lessons to learn too. Like most humans change is difficult.
We expect it to carry on as normal, then things come along to challenge that. Most are not ready for change.
But if you have the perspective that life is a journey that you are on (or choose to be on) and it is constantly changing and challenging then maybe it would be easier. It would not be such a surprise. If you accepted that evil was there to help and that death was not the end. Then the journey could actually be fun. Maybe you are not supposed to be married forever, we are meant to flow between sexual types.
