Anyone who actually believes in Karma must acknowledge how capricious, inconsistent, and cruel it appears to be. There are many seal hunters, so why these five? And why not deer hunters? Hell, why not rapists and murderers? Why do so many evil people live long healthy lives, while young children suffer from starvation or die from cancer?
There's no cosmic justice. If karmic justice existed, you would be chocking on your Big Macs.
