I believe that the whole album is about the salvation of his soul and all the mistakes he made. This may be refering to illuminati. This is a fact I thought about it when I started read the lyrics of their songs and I understood that they reffering to illuminati several times and also bmth in album "sempiternal" tell us that hell follows if illuminati complete their goal but also hell follows illuminati when they judged by people/god (i don't know what if these two). The title of their album "There Is a Hell, Believe Me I've Seen It. There Is a Heaven, Let's Keep It a Secret." is talking about Illuminati is hiding the fact that we are a spiritual being so "lets keep it a secret".
The Hell he is talking about is the controlled and manipulated world we live in, not to mention the music industry.
