Man stabs in the back

There is beautiful grass outside. It does not know any right and wrong, and it’s still beautiful. It is not depressed. You do not see any animal raping any other animal. You do not see ethnic cleaning in jungles. You do not see that one animal was so violent that it caused any other species to go extinct.
You do not see organized wars amongst trees. Now, they don’t have a sense of right and wrong and yet they are alright.
