Andre Gide

I think this quote is saying that people can kill each other, without actually killing them. People are evil and will kill each other financially and other more discreet and cynical ways. Maybe, almost slowly killing them physically by destroying by other methods until the no longer have the will to live. Then, you can not get charged with murder and you still make gains of some sort. People will lie, steal, and do many other things to get ahead and killing them some way is definitely not out of the question. Big businesses slowly choking the life out of little businesses and their owners.
