They were looking for trees and trying to catch a deer for dinner. Because they accidentally caught the wrong animal you feel they deserved death? You're not one of those weird people with twelve cats that you call children and no human friends are you?
No, I have one dog, and yes she is a child, I also have human friends, and I do like animals more than people. A lot more.
If they wanted a deer, then they should have shot a deer. Instead that caught a tiger cub and killed it, then Mother Nature gave them what for. Mother nature teaches stupid humans valuable lessons all the time. Pity they don’t seem to learn very often.
