I know they have to eat, just like when I watch wildlife programs and the big cats chase down some mothers new born calf/ antelope infant whatever, a few minutes before they allowed you to watch her give birth to this beautiful little thing.... I absolutely love the big cats and admire their awesome beauty, but I change the channel, so I do not have to watch lol.
I understand nature can be a *&%$# sometimes. And yes I eat meat, fish, so forth, I would not if I had to go and kill it, and look at faces , if it's already packaged and no longer appears like a critter. I will eat it. LOL,
Feeding your guy pre- killed, is much better tan picking out a cute rat, or piggy, bunny, or mouse that you have gotten to know or have watched grow, and hand it over to something that you know is about to horrify it as it is being crushed/ squeezed to death,,,, Some people run to watch the whole thing, thats what I do not like.
Also I totally agree with your Bambi senerio, ARM the beasts, lol, give them a fair chance.
** Killing for much needed food is one thing if done in a humane way, but killing for the sport of hanging some animals head on your wall or making a rug out of it , or stuffing it to show others your trophy is WRONG in my mind.
As far as the aliens, funny, I saw a twilight zone segment with aliens that made friends with us and were organizing trips back to their planet, people were lining up to get to go..... hehehehe
As the alien ship doors were about to close a person aboard happens to see a "COOKBOOK" belonging to the aliens,,,,, and relizes where they are going and why , LMAO 
Talk about horrified, could you imagine.
