"Think'st thou that I, who saw the face of God"

I use quotes from the Christopher Marlowe play The Tragical History of Doctor Faustus.

Faustus asks Mephistophilis, representative of Lucifer, why is he out of hell. In which Mephistophilis replies:

"Why this is hell, nor am I out of it.
Think'st thou that I, who saw the face of God,
And tasted the eternal joys of heaven,
Am not tormented with ten thousand hells
In being deprived of everlasting bliss?"

It means that Mephistophilis has great knowledge about God, and that he desires to return to Heaven. This brings to mind Lucifer's role as the Fallen Angel.

In life's terms, it can mean:
Are there any choices that we regret and cannot change?. or
Do we really like to hate and not love anymore? or
Is life a torment?

Some might actually sympathise the Devil, not for being proud but pointing out what's true in mankind.
