What's the humane and reasonable thing to do?

Im really excited to begin hunting and I'm planning on hunting coyotes. I've seen videos of people hunting coyotes and I've seen some of them don't die on the first initial shot. What would be the human thing to do? Should I try shooting it again? Walk up to it? What should I do? For more context I haven't hunted before and want to see what people think would be the human thing to do.
