For ungodly creatures like Dante, to Fall would be the greatest sin their kind could possibly commit.

There was a Glory in the Flight that came before it, an Honour in the Fight, but the Fall ultimately eradicates all Pride that might have come with it. After all, there was no use for the Fallen. They were worse than the Damned, having sung in the Bestowed's choir. They were lower than the lowest, doomed for Death.

Yet, Dante could not regret the Fall. Not when it resulted in meeting you.
