You are making a lot of assumptions, which seem taylored to bolster a particular worldview, rather than be based in fact. In particular, you assume
1. People differ vastly in their innate ability to follow societal rules.
2. The justice system is able to distinguish between people who make simple mistakes, and people who are unable to follow society rules.
3. The above is a big factor in sentencing.
While there is evidence that some aspects of behavior are innate, there is also a huge literature linking the environment a person is raised in, and their tendency towards crime. Furthermore, sentencing is generally extremely inconsistent by any standards, so it is very unlikely that sentencing would fit your criteria for being lenient to the right people. Finally, it's hard to think of sentencing criteria that fit the criteria you propose, and are also objective.
