I think that this is a quite well written poem, which flows good too. I'd recommend you to insert some commas here and there still though so the flow gets even better. I liked the detailed description because it helps the readers imagination and I think that the emotions are really powerful.

"Only because he lived in a world of lust.
And everything he had got rust,
Everything he once enjoyed ALL ( delete) got lost,
Just because he lived in a World of Lust!"
I think if you take the All it would sound better since you already had everything.
As usual, I like the message. But I didn't think the capitalisation in some parts of the beginning worked, it somehow disrupted the flow. And the subtle rhyming in the end quite frankly ruined it for me. But seeing as this was written about a year ago,I can really see the big improvement. Typo on losing by the way. Still a great read though. Keep it up :)
