Ok so i want to understand your position. Is it a matter of principle that it is never ok to use violence against someone for committing fraud? For example is it immoral to use threats of force to seek restitution for acts of fraud committed against you?
Thanks for your curiosity.
Yes, if your sister steals your toy, you can't start hitting her. You can steal it back though.
It's a principle indeed, fairness. Leveling up violence is not fair. Initiating the use of violence is immoral. The moment we accept this we will get a better world, and you also get a better life if you accept this. Don't hit your fellow man, don't hit your children, you will be happier.
Threats of violence I'm not sure about as it is not violence but words. I think it is not immoral but it certainly is a warning that this person could be immoral.
What do you think?
Ps: Sorry moderator for the offtopic split you had to do.
