Meaning of "Deranged" by Exodus

The lyrics of "Deranged" delve into the theme of mental illness and the failure of the system to properly address it. The protagonist of the song is a troubled individual who experiences a disconnect between reality and their own twisted thoughts. Despite being aware of their own derangement, they are deemed "ok" by psychiatrists and eventually released back into society after serving a short period in a mental institution. This highlights the inadequacy of the system in dealing with individuals who pose a danger to themselves and others due to mental illness. The song ultimately critiques the inability of the system to effectively treat and rehabilitate those who are mentally disturbed, leading to a cycle of violence and destruction.
