There is a difference between wanting food you think is delicious and killing something for that reason and taking pleasure in the process of killing something. In one scenario the killing is a necessary evil in the other it’s the whole point of the process.
Aside from that the fact that so many people do pay “hitmen” should tell you that they do not enjoy the killing part, because otherwise they’d do it themselves.
I’m not sure what the difference between those two options is. But those aren’t the two options I was talking about. There are people that enjoy the process of killing things. There are people that like to eat dead animals but do not enjoy the process of killing the animal. Those are two different things in my mind.
