Yep, you are absolutely right!

e.g If a wild cat is hunting your domestic animals, she is not doing this for pleasure instead she may be doing so to feed her kids....So why we should hunt/hate her.

I love it when nature documentaries show this. At first you see a big lion or another predator kill a poor little gazelle, and everyone gets upset at the lion. In the next scene you see her feeding it to the cure little cubs, and suddenly everyone is okay with it after all.
