Bewildered

He is sinking in the fiery deluge/going near to fearsome death...

May be Satan or Beelzebub or it has any other name,
I thought him good,but he didn't remain the same.

Alas,he was my dear,
And he is going to be killed by his own spear.

Though Lucifer used to show light in Heaven,but it was me,who did it for you,
But OMG again and again darkness seems more familiar to you.

Oh again I'm trying to stop the race,
Because you've made it all a mess !

Each day each night I cry upon my fate,
Did you kill me to win a bet?

The world is so rude that I wonder,
You also proved it,that I've made a blunder.

I'm gifted a dismal face,
And your world is a total mesh.

I can't get out of this and I'm dismayed.
Its not at all a glorious Enterprize that you've made.

I'm still perplexed and its a doleful state,
Can I consider you as the best mate??
