In my misspent youth I got into an altercation that escalated to the point of me being charged with attempted manslaughter[1].
The police picked me up late on a Friday and I spent the weekend in a Nassau county jail. It changed my life...
When I hear people dismiss the power of deterrence it makes me realize they don't have the particular category of cognition that was thrust upon me by my own impulsiveness. Seems like you have a similar context as I -- now may we both never lose it.

[1]: yes; attempted manslaughter -- in New York Penal Law, "Attempt" is a separate article that can be applied to any crime: "§110.00 -- Attempt to commit a crime. A person is guilty of an attempt to commit a crime when, with intent to commit a crime, he engages in conduct which tends to effect the commission of such crime."
