They care about their own pleasure and they get some from eating fat and sugar so that's all they want to do.  They have no consideration for anyone else (unless it will somehow get them more food)  They do feel shame and self loathing for what they are and what they do which makes them angry, but not at themselves, at anyone that reminds them of what they are. Overall, nasty pieces of work, food actually does a good job in identifying these worthless sacks of shit but bloating them up for the world to see
