Let's start with the old saying "Don't do the crime if you can't do the time." This is the classic risk vs reward equation in a different form or distilled down to:
"Is it worth it?"
When it comes to risk most people underestimate it, so assume that you will as well. You will likely get away with speeding, or littering---but murder?? There are so many ways to get caught with the science of modern forensics, surveillance & alarm systems, cell phone gps tracking etc.
So let's assume that somehow you will get caught. For a financial crime you will likely only do 5 years or less but if you can hide the cash and then do the 5 years then maybe it's worth it.
For drug crimes small dealers may get away with it and make a good living for years or even decades possibly swaying some into doing this crime but for large scale dealers both the risk and reward go way up making this a very risky choice to make.
For violent crimes there's usually little financial payoff but sometimes an emotional one and high penalties. So ask yourself "Did they really do you that much wrong?"
Then there's the possibility of karma or accountability to a higher power.
Best advice is:
Don't do it unless you have to, for whatever reason, but understand there's usually no turning back. Once you make the decision to head down this path one thing leads to another and you may not like the place that you wind up. There are a lot of people locked up because they forgot that one little thing....
