When a rabbit eats their young there is likely a reason for it...unfavourable environmental conditions or a sickness in the kits. They do it because they know their babies will not survive. We are animals. We may be different from all the others but at our core we're just another species tromping through the planet. Doesn't mean we can't have meaningful happy lives or show great altruism for others, but there is also plenty evidence of altruism throughout the animal kingdom. I'm a big believer in being a good person and trying to become a better person every day, and of seeing the good in others even when it is difficult, but I also think we overstate our importance quite a bit.
