“...complained in a letter to the prison service that his coffee is served cold, he does not have enough butter for his bread, and he is not allowed moisturiser.”
Spoken like a textbook sociopath. Absolutely incapable of feeling anything akin to regret or empathy. He’ll go to his grave never feeling a moment of remorse for the crimes he has committed.
Hopefully he goes to his grave long before his prison sentence expires.
