Sin is all the same to God when He looks at it in the light of it being against His will. Thinking about killing someone is as bad as doing it. It is also the same in His desire to forgive sin. This is the nature of sin.
When it comes to the practical application of how to deal with sin and it's consequences then the Levitical laws suggest how to deal with it in various manners according to how God see's it's severity. This falls under jurisprudence.
So, god's a dictator. And god views the guy who murders his entire family the same as the guy who commits adultery? I don't care if your god is real, I still wouldn't worship such an immoral dictator. And I'm glad that secular values are holding your religion in check.
