And the gradient of sentencing for the convictions -- defrauding people of $1 gets you less jail time that defrauding people out of $100k, which gets you less jail time than defrauding people out of $100M.
Fake numbers but say you shot and killed someone -- the law (and related sentences) can accomodate a wide variety of scenarios which will lead to a wide variety of punishments. E.g. if you were cleaning a gun and it went off, you could be charged with involuntary manslaughter and face 5 years, or if you were in a fight and pulled a gun you could be charged with voluntary manslaughter and face 10 years, or if the fight seemed avoidable it could be a 3rd degree homicide charge facing 15 years, or if you shot them will robbing a bank, it could be a 2nd degree homicide facing 20 years, or if you planned an assassination and shot someone, it could be 1st degree homicide where you would face life.
There's a binary "guilty / not guilty" but on the guilty branch, each of those sentences has enhancements that will determine your length of incarceration. Was this your first crime? Were you on drugs? Was the robbery over $5 or over $50k? and so on and so on.
Murder I, Murder II, (voluntary/involuntary) Manslaughter, etc.
To the extent grey areas exist, they are accounted for in a gradient of crimes, each of which has a binary degree of guilt.
