That's probably the simplest, most logical explanation I've heard yet. I like it. :)
Then again, the veil of ignorance would fail me here. If I could have been on the prey side instead of the predator side, I'd probably want to change the rules a bit. I dunno. Maybe give the prey a really, really great life, even if it ends in our meal. Hmm... now I'm thinking about the simulation hypothesis... maybe we're the meal. :)
You would want to change the rules; however you'd be thankful for those side loaded, 340 degree seeing eyes. :-)
