I find it extremely ironic that you are making that point. What you are doing is precisely declaring a law about a complex and controversial issue to be invalid because there is an "universal and absolute argument" (aka, you think so) against that law. That's not how things work. Why would the things Jack the ripper thinks and agrees with be irrelevant and yours be "universalized arguments" that everyone must accept?

EDIT:

>According to my argument, it would be fine to use lethal force against Jack the Ripper initiating violence

Precisely. According to your argument. Not a universal truth.
