You think of yourself as a person with at least one foot on the path to enlightenment. You rationalise the killing as being acceptable considering the nature and insignificance of the victims.
Yet the cockroach is to you as you are to the sentient entity known as Everything, aka Reality. The ant knows you as well as you know Everything. The mouse in the mousetrap understands its agony as well as you understand the trials and tribulations that Reality inflicts upon you. Do you want Everything to treat you as you treat those you believe are “lower” forms of life?
Actually, the sentient entity known as Reality doesn’t always treat humans in ways that humans would describe as “gentle” or “loving” or “respectful”. Let’s not forget that every thing is as much a part of Everything as anything, which is why Everything treats every thing equally. The so-called “acts of Everything”, including droughts, hurricanes, tsunamis and earthquakes, continue to cause misery and death to humans, cockroaches, ants and mice indiscriminately.
What makes humans a “higher” form of life than, say, mice? It’s true that mice don’t build cathedrals as well as humans do. But humans don’t scurry or gnaw or reproduce as well as mice do. In what way is cathedral-building a worthier activity than gnawing, or reproducing for that matter?
