Is Harley doing his job the best to his abilities? Sure, but that doesn't mean he can't be questioned regarding his morals. In my opinion, getting a known child molester off on a technicality, is absolutely atrocious. Basically, Harley is allowing this person to go free, in order to harm other children, so he can win another case and fill his pockets. How does Harley rationalize this? Its an important question. Its obvious that Harleys morals and ethics are DIRECTLY CONNECTED to his job.
Guess what? MOST jobs are connected and directly intertwined with moral and ethical decisions, including doctors, nurses, social workers, teachers, judges, and, yes, EVEN lawyers, etc. Most of us would be beside ourselves if we let a known child molester off with a technicality, only to find how he raped and murdered a child. In Harley's eyes, he just did his job. However, there is something to be said of someone who can shrug this off as "oh well, I was just doing my job." Most of us would feel extremely guilty, yet, Harley does it with zero conscience. That 100% says something about his personality and who he is as a person.
Now, on the one hand, Harley is just doing his job. However, on the other hand, from a purely moral point of view, and based on what we know about morality, his behavior would be considered immoral. Just because something is part of the legal system, it doesn't mean its not immoral. Many legal matters are immoral, despite them being legal. For instance, in some cultures an adult male can marry and have sex with an 8 year old. Its legal. However, there is enough evidence to suggest that young children suffer from all sorts of issues when they have sex with adults. So, sleeping with an 8 year old may be legal, but Id still deem it immoral. Similarly, Harley is not doing anything illegal and he is doing his job; nonetheless, in my opinion, Id still constitute it as immoral behavior.
People keep saying, "Well, he is doing his job within legal parameters." Great, but as I stated above, actions deemed legal by the law can still be immoral. Its quite obvious that many aspects of law are not based from a moralistic perspective.
