Putting a rock on a bird to keep it warm? Bad
Sitting on a bird to keep it warm? Also bad
Leaving a helpless bird in the rain? Sure, bad
Leave same bird to the wolves? Good?
It is just part of the cycle.
You realize that nature cannot be beat, and trying to beat nature is a pointless task. You are, after all, part of nature as well. And you and nature have a lot in common. For example, neither of you show mercy towards the helpless no matter how simple it could be to right the wrong that has happened to them.
Also, you and nature are both cowards. Actually, that can only be applied to one of you. You should meditate on which one.
