See.. that's the problem.. you say the circumstances matter.
You don't mourn a person that made a living hunting wild dangerous animals and was killed.
Why?
My children are chasing, herding and roping a dangerous animal as well, and they do it as a job as well. So why would you treat that differently?
Is it because you eat cattle.. and therefore its acceptable.. and you don;t eat elephant so that's not?
Why the difference.
Rational people, using the rationale that you propose.. that someone making a living dealing with dangerous animals.. basically get what he deserves....
Should use the same rationale with cattle as well as elephants.
