Of course it's totally valid to make whatever decisions you like, but there is something disconcerting to me about how we judge our hands clean as long as we pay someone else to do horrific things to animals. Personally I think I probably do worse moral harm than killing an elephant every time I buy a dozen eggs or a Costco rotisserie chicken.
An average African elephant weighs 12,000 pounds. A roaster weights about 10. As a yardstick, someone who goes out and kills 1200 chickens just for joy is probably a shittier person than someone who kills one to eat.
