Ok? Welcome to earth. We are a violent species. Sometimes people die violently. What’s your point?
Lawful killing is, by definition, legal. It’s also justified in certain situations.
Disagree? Cool, so don’t work for the police or Cellebrite lol, but don’t try to impose your idiosyncrasies on others.
If your ethics are “people die so I might as well partake in killing them” I suspect you haven’t really thought this through very thoroughly
