But even in his mind right now, there is pain. Memories he unusually put in the back of his mind, surfaces again. 

"Is this also part of the tribulation?" he thought to himselkf

And there is many thoughts, many painful memories

The regret. The unfulfilled desires. The broken dreams. 

All the things he wished he would have done, all the things he wished he had never done, things he should do and things he shouldn't.

Azief knows this. But he could not stop the memories from rushing forwards, each one is trying to weaken his resolve
