I realize that this is the thoughts of a psychopath, but there must be people out there who do not feel a remote level of remorse killing other human beings who have been convicted criminals that cannot be rehabilitated and would enjoy satiating a primal need.
I enjoy living in a safe and considerate society, and take care of my elderly neighbors and family, I call my friends when they feel ill, yet I also enjoy the thoughts of murdering pedophiles and serial killers as a strange justified bloodlust.
I understand we all like to think most people want live in a peaceful and caring society, but to put it bluntly there are many people out there who do not give a fuck about any of that and enjoy seeing suffering to make themselves feel better. Having limp-wrist peace-and-love rose-tinted glasses pacifists are not going to protect you from those monsters.
